UPDATING revision 119412
1Updating Information for FreeBSD current users 2 3This file is maintained and copyrighted by M. Warner Losh 4<imp@village.org>. See end of file for further details. For commonly 5done items, please see the COMMON ITEMS: section later in the file. 6 7NOTE TO PEOPLE WHO THINK THAT 5.0-CURRENT IS SLOW: 8 FreeBSD 5.0-CURRENT has many debugging features turned on, in 9 both the kernel and userland. These features attempt to detect 10 incorrect use of system primitives, and encourage loud failure 11 through extra sanity checking and fail stop semantics. They 12 also substantially impact system performance. If you want to 13 do performance measurement, benchmarking, and optimization, 14 you'll want to turn them off. This includes various WITNESS- 15 related kernel options, INVARIANTS, malloc debugging flags 16 in userland, and various verbose features in the kernel. Many 17 developers choose to disable these features on build machines 18 to maximize performance. 19 2020030824: 21 ATAng has been committed. You need to build world as sys/ata.h 22 has changed, and userland atacontrol depends on it. 23 If you use ATA SW raids you need "device ataraid" in your kernel config file, as it is no longer pulled in automatically. 24 2520030819: 26 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 27 Among other things, this changes the device enumeration to be 28 closer to Solaris. Be aware that, this can even cause the machine 29 to not boot without manual intervention before the fstab is adjusted. 30 3120030728: 32 All current USB and Firewire quirks in da(4) have been deprecated 33 and will be removed for 5.2. If this causes failure for your 34 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 35 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 36 so the quirk can be re-enabled. 37 3820030722: 39 FPU-less support has been removed from FreeBSD. Chances are you won't 40 notice. 386+387 support should still work after this change, but 41 it is now a minimum requirement for the i386 port that you have real 42 FPU hardware. 43 4420030714: 45 Some people are having problems with changes related to /rescue. 46 If you are building -j N, you will need to define NO_RESCUE. Others 47 will need to define it if /rescue has issues with their environment. 48 People should report those issues to current@. 49 5020030711: 51 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 52 across this point. Further, it might be a good idea to remove 53 /usr/obj. 54 5520030613: [retrospective] 56 There was a small window in which sed(1) was broken. If you 57 happen to have sed(1) installed during that window, which is 58 evidenced by an inability to build world with the failure 59 given below, you need to manually build and install sed(1) 60 (and only sed(1)) before doing anything else. This is a one- 61 time snafu. Typical failure mode: 62 63 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 64 targmatch.h:7:1: null character(s) ignored 65 targmatch.h:12:1: null character(s) ignored 66 targmatch.h:16:1: null character(s) ignored 67 : 68 69 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 70 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 71 usr.bin/sed/process.c). 72 7320030610: 74 Remove deprecated locale names and transition period code 75 for them, finishing switching to the new scheme. Check your 76 LANG environment variable. 77 7820030609: 79 CCD has been changed to be a fully GEOMified class. Kernel 80 and ccdconfig(8) needs to be in sync, this is particularly 81 important to remember beforehand if your source tree is on 82 a ccd device. Consider making a copy of the old ccdconfig 83 into /boot/kernel.good or wherever you keep your backup 84 kernel. 85 8620030505: 87 Kerberos 5 (Heimdal) is now built by default. Setting 88 MAKE_KERBEROS5 no longer has any effect. If you do NOT 89 want the "base" Kerberos 5, you need to set NO_KERBEROS. 90 9120030502: 92 groff has been updated. If you try to do a buildworld and 93 get an infinite loop in troff, update to May 4th or newer. If you 94 have a newer kernel than userland, you may need to set the OSRELDATE 95 to 500110 in your environment before starting a buildworld. 96 9720030501: 98 The old rc system has been removed. Please report any problems 99 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 100 Your personal versions of these files will not be removed, so you can 101 continue to use them. However, you should take great care when updating, 102 especially when using mergemaster, since the compatibility code that 103 utilizes these old scripts has also been removed. 104 10520030423: 106 A bug has been fixed in /dev/devctl which would cause devd 107 to hang on boot, were it not for a workaround in devd. The 108 work around in devd will be removed around 20030507. You 109 have until then to upgrade your kernel before updating 110 userland. In general, you should have a userland and 111 kernel that's in sync with each other. However, given the 112 effects of this bug (hang on boot when starting devd), some 113 allowances are made. 114 11520030329: 116 Alphas with libc from between 20030312 and 20030329 exhibit 117 floating point exceptions (FPEs), most notably in awk(1) 118 while upgrading the system through a buildworld. 119 120 So, to successfully upgrade your Alpha, you must either 121 downgrade your libc.so to a pre-20030312 version, or update 122 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 123 to CFLAGS, then forcibly rebuild and install libc: 124 125 cd /usr/src/lib/libc && \ 126 make cleandir && make obj && \ 127 make -DNOMAN -DNOPROFILE all && \ 128 make -DNOMAN -DNOPROFILE install 129 13020030208: 131 sendmail 8.12.7 has been imported. It has one important 132 change for IPv6 users. The default submit.mc now uses 133 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 134 used to connect to the MTA. Users on IPv6-only machines 135 will need to edit /etc/mail/submit.mc appropriately. 136 13720030128: 138 NODEVFS option has been removed and DEVFS thereby made standard. 139 This makes all references to MAKEDEV obsolete, and they should 140 be removed when convenient. 141 14220030126: 143 The name of the device for the ofw console has changed, sparc64 users 144 must run mergemaster to update their installed /etc/ttys. 145 14620030125: 147 The scheduler framework has grown a second scheduler and consequently 148 you must specify one and only one scheduler in your kernel config. 149 The cvs config files have been updated to use the old scheduler 150 which may be selected via 'options SCHED_4BSD'. If you would like 151 to try the new, much more experimental, scheduler please try 152 'options SCHED_ULE' and contribute to the arch@ discussion. 153 15420030115: 155 A new version of the wi driver has been imported into the tree. 156 One now must have device wlan in the config file for it to operate 157 properly. 158 159 In addition, there have been some changes to how wi devices are 160 configured for point to point links to bring it more in line 161 with the former way of doing things, as well as compatibility 162 with NetBSD. 163 16420021222: 165 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 166 used an incompatible form of ABI for returning structures and unions 167 which FreeBSD's GCC maintainers were not aware of relative to previous 168 versions of FreeBSD. We have gone back to the ABI for now, and any 169 code compiled which is required to interoperate with other code (not 170 built at the same time) returning structs or unions should be 171 rebuilt. 172 17320021216: 174 A name change in /etc/netconfig has been reverted to stay 175 compatible with suns TIRPC and also with NetBSD. You need 176 to run mergemaster after make world. A new libc does still work 177 with an outdated /etc/netconfig for some time, but you'll get 178 a warning. This warning will be removed in 20030301. 179 18020021202: 181 The recent binutils upgrade marks a kernel flag day on 182 sparc64: modules built with the old binutils will not work 183 with new kernels and vice versa. Mismatches will result in 184 panics. Make sure your kernel and modules are in sync. 185 18620021029: 187 The value of IPPROTO_DIVERT has changed. Make sure to keep 188 your kernel, netstat, natd and any third-party DIVERT 189 consumers in sync. 190 19120021024: 192 Old, compatibility slices have been removed in GEOM kernels. 193 This means that you will have to update your /etc/fstab to 194 not use disk devices of the form /dev/ad0a. Instead, you 195 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 196 partition really is on. The old device names have gone 197 away, so if you use them anywhere else, you must also adjust 198 those uses. (This doesn't affect the disks formatted in 199 the ``dangerously-dedicated'' mode.) 200 20120021023: 202 Alphas with kernels from between 20020830 and 20021023 and/or 203 rtld (ld-elf.so.1) older than 20021023 may experience problems 204 with groff while doing a buildworld (kernel: "out of memory", 205 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 206 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 207 208 So, to successfully upgrade your Alpha, you must either 209 upgrade your kernel and rtld first (which might be a bit 210 tricky), or avoid running the bootstrapped groff during the 211 "transitional" buildworld. To avoid running groff during the 212 transitional upgrade run make buildworld with -DNOMAN, 213 -DNO_SHAREDOCS, and -DNO_LPR. 214 21520020831: 216 gcc has been upgraded to 3.2. It is not all binary compatible 217 with earlier versions of gcc for c++ programs. All c++ 218 programs and libraries need to be recompiled. 219 220 Also, if you encounter g++ issues, rm /usr/include/g++/* before 221 doing an installworld to make sure that stale files are removed. 222 22320020827: 224 Our /etc/termcap now has all the entries from the XFree86 xterm 225 almost unchanged. This means xterm now supports color by default. 226 If you used TERM=xterm-color in the past you now should use 227 TERM=xterm. (xterm-color will lead to benign warnings). 228 22920020815: 230 A "bug" in gcc(1) that was hiding warning in system headers was 231 fixed. It's probably time to add -DNO_WERROR to your make line 232 again. 233 23420020729: 235 COPY is being deprecated. The 20010530 change was reverted, as 236 it causes far more pain than was expected, and to always compare 237 before installing, please use INSTALL="install -C" again. The 238 -C option is now silently ignored when used with the -d option. 239 24020020702: 241 Problems with libc_r clients like KDE and GNOME have been resolved. 242 There are still some minor problems with some signals but the 243 system is stable enough for general use again. SMP is less so than UP 244 but each can successfully complete multiple buildworlds. 245 Libkvm needs to be recompiled due to KSE. 246 24720020701: 248 Now would be a bad time to upgrade. Something in or near the 249 KSE commit totally broke programs using libc_r like KDE and 250 GNOME. 251 25220020511: 253 The k5su utility installed as part of Kerberos 5 is no longer 254 installed with the set-user-ID bit set by default. Add 255 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 256 with the set-user-ID bit set. 257 25820020510: 259 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 260 Unfortunately our native GDB (at version 4.18) does not understand 261 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 262 generated debugging information for our native GDB. 263 26420020510: 265 Due to the way CVS works, it may not properly update src/contrib/gcc 266 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 267 and then do a cvs update. 268 26920020421: 270 When exec'ing set[ug]id executables, the kernel now ensures that the 271 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 272 27320020404: 274 New sendmail startup scripts have been installed to make it 275 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 276 variable sendmail_enable to "NO" no longer prevents any sendmail 277 daemons from starting. Instead, either set sendmail_enable to 278 "NONE" or change mta_start_script to a script for starting 279 an alternative MTA. Setting mta_start_script to "" will 280 also prevent any MTA from being started at boot. 281 28220020403: 283 UCONSOLE is no longer a valid kernel option. 284 28520020315: 286 FreeBSD 5.0 DP-1 was basically branched today. 287 28820020225: 289 Warnings are now errors in the kernel. Unless you are a developer, 290 you should add -DNO_WERROR to your make line. 291 29220020217: 293 sendmail 8.12.2 has been imported. The sendmail binary is no 294 longer a set-user-ID root binary and the infrastructure to support 295 command line mail submission has changed. Be sure to run 296 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 297 and /etc/mail) and read /etc/mail/README for more details. 298 299 Due to the import of sendmail 8.12.2, a new user and group are 300 required in order for sendmail to run as a set-group-ID 301 binary. A 'make installworld' will use the new user and group 302 to set the owner and group of /var/spool/clientmqueue and will 303 fail if the new user and group do not exist. The 'smmsp' user 304 and group must be merged from src/etc/group and 305 src/etc/master.passwd before using 'make installworld'. 306 'mergemaster -p' will do this. You may need to install 307 mergemaster before this will work if you are updating from a 308 very old version of current. The updating recipe has changed 309 as of this date. 310 31120020112: 312 The preferred configuration method for PAM is now /etc/pam.d/ 313 rather than /etc/pam.conf. If you have an unmodified 314 pam.conf, just delete it after your next mergemaster run. If 315 you have local modifications, you can use 316 /usr/src/etc/pam.d/convert.pl to incorporate them into your 317 /etc/pam.d. 318 319 Please see the following url for more details: 320http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 32120011229: 322 If anyone here is already using the new rc.conf(5) variable 323 networkfs_types, please note that it has changed 324http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 325 32620011220: 327 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 328 started out its life in the ISDN4BSD project as an offspring 329 from sys/net/if_spppsubr.c, which eventually got a life of its 330 own. All the accumulated features and bugfixes of the i4b 331 version have now been merged back into the base system's 332 version now. The only user-visible change resulting from this 333 is that i4b's sppp(4) interfaces are to be managed with 334 spppcontrol(8) again, since ispppcontrol(8) has been retired 335 as well. (There has never been rc file support for 336 ispppcontrol in -current, but only in -stable. That will be 337 reverted by the time the changes are MFCed.) 338 33920011215: 340 The fdc(4) driver has been updated and now automatically 341 recognizes media in `standard' formats (like 1440 KB and 342 720 KB for a 3.5" high-density drive) when accessing the 343 default device node (e. g. /dev/fd0). The old variety of 344 floppy device nodes /dev/fd*.* is no longer present by 345 default, devices can be created (in DEVFS) on demand. They 346 will need to be customized then for `odd' densities using 347 fdcontrol(8). 348 34920011209: 350 The bugs in procfs' debugging support code have been fixed, 351 and truss(1) now works again. 352 35320011207: 354 Daily security checks have been split out to use the periodic(8) 355 scripts. Some change in configuration may be necessary. Please 356 see 357http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 358 for details. 359 36020011204: 361 sos added VCD/SVCD support to ata driver and that needs the 362 kernel and burncd to be in sync. 363 36420011203: 365 The procfs pseudo-filesystem has now been converted to use the 366 pseudofs framework. If you have 'options PROCFS' in your 367 kernel config, you'll need to add 'options PSEUDOFS' if it's 368 not there already. 369 370 This change temporarily breaks truss(1); use ktrace(1) instead 371 until the issue has been resolved. 372 37320011202: 374 A security hole in OpenSSH involving `UseLogin yes' has been 375 patched. 376 37720011126: 378 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 379 after this date. You need to do this only once. 380 38120011103: 382 Most of the awk issues have been resolved. Some rough 383 edges may be left, but for the most part things should be 384 back to "normal." For CURRENT's usual definition of "normal." 385 38620011030: 387 Awk has been upgraded to the one true awk from bell labs. Expect 388 choppy waves in the upgrade process. 389 39020011030: 391 The asr driver problem has been resolved. 392 39320011027: 394 Due to changes in other parts of the system, the asr driver 395 now causes the system to panic on boot. Do not use it pending 396 correction. Comment it out of any kernel config file that you 397 try to use from this date forward. 398 39920011025: 400 When crossbuilding, use TARGET=xxx where you used to use 401 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 402 unless you are changing both of them. To cross build pc98 on 403 an alpha, for example, you need to set TARGET=pc98 and 404 TARGET_ARCH=i386. 405 40620011001: 407 The kernel interface that burncd depends on has changed. 408 You must recompile both the kernel and userland applications 409 at the same time. 410 41120010929: 412 When crossbuilding, please set TARGET_ARCH rather than 413 MACHINE_ARCH to indicate the target. In the future, one will 414 set TARGET_MACHINE where you set MACHINE now. At the moment, 415 setting MACHINE alone for same MACHINE_ARCH machines works 416 (eg, you can build pc98 on an i386 machine and vice versa). 417 41820010927: 419 Some weird problems result from using ACPI on some machines. 420 To disable ACPI you can add 421 hint.acpi.0.disabled="1" 422 to /boot/loader.conf (or by putting set X=Y at the boot 423 loader "ok" prompt). 424 425 Alternatively, you can remove it from /boot/kernel/acpi.ko 426 or use the MODULES_OVERRIDE function in your kernel config 427 file and not list acpi in that list. 428 42920010924: 430 The buildworld has been fixed. You may need to install 431 the 4.x compatibility libraries for some old binaries 432 to work. Add COMPAT4X=true to your /etc/make.conf to 433 get them installed on every installworld, or execute the 434 following to get them installed only once: 435 cd src/lib/compat/compat4x.<arch> 436 make all install 437 You will see ``__stdoutp undefined'' until you do this. 438 43920010919: 440 There's a bug in the world build process. The cross-tools 441 are build with the NEW headers, but the OLD libc.a. This 442 leads to all kinds of problems with the new libc. A temporary 443 workaround is to add 444 CFLAGS="-O -pipe -D_OLD_STDIO" 445 before building world when upgrading from 4.x to current. This 446 can be removed afterwards. 447 448 A proper fix to the buildworld target is needed. 449 45020010918: 451 Peter has committed his new kthread nfs client/server code. 452 NFS may be unstable after this date. 453 45420010912: 455 KSE has hit the tree. Lots of things are now different in 456 the kernel. While a few problems were introduced in the 457 initial commit, most of the major ones have been found and 458 corrected. 459 46020010901: 461 In OLDCARD, CardBus bridges appear to be stable. The work 462 arounds described in the 20010604 entry are now no longer 463 necessary and will be ignored. Most insert/remove problems 464 have been rectified around this date. 465 46620010823: 467 named now runs as user bind and group bind rather than as 468 root. If named_enable is set to YES in /etc/rc.conf, ensure 469 that user bind is available in /etc/passwd (using vipw(8)) 470 and that group bind is available in /etc/group. Also make 471 sure that user or group bind has read (and not write) 472 permission for your name server configuration and that it 473 has read and write permission for your slave zone files and 474 directory. 475 476 If you wish to continue to run named as root (a less secure 477 alternative), add a line to /etc/rc.conf saying 478 479 named_flags= 480 48120010709: 482 The PAM libraries have had an API upgrade that is beyond 483 the ability of the shared library major number to handle. 484 It is manifested by PAM-using ports dumping core. The 485 solution is to rebuild those ports. 486 48720010628: 488 The kernel compile module has moved from src/sys/compile/FOO 489 to src/sys/${MACHINE}/compile/FOO. 490 49120010625: 492 The pccard modem issue from 20010613 has been corrected. 493 OLDCARD support is still a little weak in -current. slot 1 is 494 known not to work on some TI based cardbus bridges. Some 495 cardbus bridges do not properly detect insert/removal events. 496 IRQ configuration needs more safety belts. 497 49820010617: 499 Softupdates problems have been corrected. 500 50120010614: 502 Peter ripped out the linkerset support. You must, as always, 503 rerun config after you cvsup if you are using the traditional 504 kernel building methods. 505 50620010613: 507 pccard modems may not work with current after 20010604 date. Some 508 do, others result in panics. *MAKE*SURE* that you update your 509 config and /etc/rc.conf ala the 20010604 entry, or you will have 510 problems (this issue will be fixed, it just hasn't been yet). 511 51220010613: 513 SOFTUPDATES seem to be broken since the middle of May or so. Do not 514 use them in current. You can disable softupdates on all mounted 515 partitions, or remove SOFTUPDATES the kernel config file. 516 51720010612: 518 After Peter's commits to the hints code, people have been noticing 519 that certain devices are attached (or try to) twice. This is due 520 to having both static hints as well as a /boot/device.hints. To 521 work around this issue, please use only one or the other mechanism 522 until this bug is fixed. 523 524 Please note that a feature of config is that if you have config 525 file FOO and FOO.hints, it automatically adds FOO.hints to the 526 hints.c file, whether you want it to or not. 527 52820010610: 529 Locale names have changed to match other systems better. 530 53120010604: 532 pccard support for pci cards has been committed. You must change 533 your /etc/pccard.conf irq lines. It must match the irq used by 534 pcic device. Interrupt storms may result if you fail to do this. 535 Interrupt storms look a lot like a hang. 536 537 You must also install a new pccardd, otherwise you will get an 538 interrupt storm at card reset time (just after it tells you what 539 it is). 540 541 pccardd_flags="-I" is necessary for the time being. It tells pccardd 542 not to ask the kernel if the interrupt is really free or not before 543 using it. You can either change the /etc/pccard.conf irq lines to 544 match pcic, or add "-i X" to the pccardd_flags. 545 54620010530: 547 INSTALL=install -C is being deprecated. If you want to do this, 548 use COPY=-C instead. The former method will be supported for only 549 a limited time. If you see 550 551install: warning: the -d and -C options may not be specified together 552 553 in your makeworld, then you need to migrate towards using 554 COPY=-C. 555 55620010525: 557 It appears that vm is now stable enough to use again. However, 558 there may be other problems, so caution is still urged. alpha 559 definitely is in bad shape. 560 56120010521: 562 Minor repo damage has happened. This may cause problems 563 with cvsup of ports. If you get errors, please see 564 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 565 at the bottom for details on a workaround. The error message 566 is 567Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 568 56920010520: 570 Vm and/or swapping are busted on -current. Please be patient. 571 57220010519: 573 pccard has had much reorganizational work done to it over 574 the past few days. Everything should still work, but if 575 not, please contact imp@freebsd.org. 576 57720010517: 578 ata ioctl changed. Make sure to recompile both kernel and 579 userland at the same time. 580 58120010517: 582 New ncurses imported. 583 58420010512: 585 DEVFS is now opt out, not opt in. Barring major problems, this 586 will be the only way to go starting July 1. 587 58820010504: 589 OpenSSH has been updated to 2.9. Some defaults are different, 590 including RhostsRSAAuthentication, which changes from yes to no. 591 59220010502: 593 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 594 59520010501: 596 Building perl was broken at 02:25:25 PDT. 597 59820010430: 599 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 600 go back in the water. 601 60220010429: 603 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 604 this date, but before the correction date. 605 60620010423: 607 old fsck and new kernel interactions appear to have been fixed. 608 60920010411: 610 fsck and the kernel were changed to handle some optimizations 611 to directory layout. This breaks backward compatibility. 612 Update only if you understand that you must not use the old 613 fsck with the new kernel ever. 614 61520010330: 616 fsck has changed the meaning of the pass column in /etc/fstab. 617 Please see the cvs commit to fsck.8 or the fsck.8 man page for 618 details. It is unclear if changes to /etc/fstab are necessary. 619 62020010319: 621 portmap had changed name to rpcbind for maximum POLA in your 622 current world. /etc/hosts.{allow,deny} needs changes. nfs and 623 other rpc based programs that rely on portmapper will not work 624 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 625 62620010315: 627 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 628 and ATA_ENABLE_TAGS are no longer kernel options. They have 629 been replaced by tunables. See ata.4 for details. 630 63120010312: 632 The fxp driver was converted to use miibus. If you compile 633 fxp into your kernel statically, you will need to add miibus. 634 63520010312: 636 The wi device now defaults to BSS (infrastructure) mode 637 instead of ad-hoc. 638 63920010310: 640 /dev/urandom should be a symbolic link to /dev/random now. 641 Users of current not using DEVFS need to run MAKEDEV std. 642 ssh might not work if you don't. 643 64420010303: 645 The ed driver has been updated. It now allows mii attachments, 646 which means that you must include the miibus in your kernel if 647 you use the ed driver. 648 64920010220: 650 The problems with libc have been corrected. It is now mostly 651 safe to go back into the water. 652 65320010211: 654 The size of FILE was changed. This breaks upgrading. If 655 you must upgrade, be prepared for pain. It also breaks almost 656 all binaries that you've compiled on -current. You are warned 657 that before upgrading would be a good time to do a level 0 658 dump of your system. No, really, I mean it this time. 659 660 To get to the new system, you'll need to use the following 661 workaround. Hopefully this can be sorted out so that we 662 don't have to move this to the updating section. 663 664 To get around the installworld problem, do: 665 # cd /usr/src/usr.bin/sed 666 # make install 667 # cd /usr/src 668 # make installworld 669 If that doesn't work, then try: 670 # make -k installworld 671 # make installworld 672 67320010207: 674 DEVFS is now the default. If you use vinum, make sure that you 675 do not include devfs in your kernel as problems result. 676 67720010205: 678 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 679 Remove them from your config. 680 68120010122: 682 ****************************** WARNING ****************************** 683 buildkernel has been changed slightly 684 ****************************** WARNING ****************************** 685 KERNCONF replaces the variable KERNEL for buildkernel. You 686 should update your scripts and make.conf accordingly. 687 68820010119: 689 config has changed to allow DEV_FOO as a replacement for NFOO. 690 This requires a new config to build correctly. 691 69220010116: 693 The kernel option I386_CPU is now mutually exclusive with the 694 other cpu types. If you have an i386 system, be sure that it 695 only had this line. Remove it for all other configurations. 696 69720010110: 698 Changes to the kernel require it and burncd be in sync. 699 70020010102: 701 Everyone who has hw.sndunit set to something in 702 /etc/sysctl.conf, it is now hw.snd.unit. 703 70420010101: 705 ex and vi were broken by some changes to sys/queue.h. If you 706 have a bad vi, you will see make buildworld fail with a core 707 dump while building termcap. You can work around this problem 708 by adding -k to your make buildworld. This will cause the 709 build to complete and install a new vi. Once that's done, you 710 can rebuild again without the -k to pick up anything that 711 might have been ignored by the -k option. 712 713 Others have suggested that you can just rebuild libc if your 714 vi/ex is dynamically linked, but I've not received any reports 715 of this working. 716 71720001228: 718 There have been some changes to libcrypt in -current. The 719 libscrypt/libdescrypt symlink silliness is gone and the installed 720 libcrypt is fully functional. Be aware of this. 721 72220001218: 723 Linksys Fast Ethernet PCCARD cards supported by the ed driver 724 now require the addition of flag 0x80000 to their config line 725 in pccard.conf(5). This flag is not optional. These Linksys 726 cards will not be recognized without it. 727 72820001205: 729 Important new FreeBSD-version stuff: PAM support has been worked 730 in, partially from the "Unix" OpenSSH version. This requires 731 adding the following in pam.conf: 732 733 sshd auth sufficient pam_skey.so 734 sshd auth required pam_unix.so try_first_pass 735 sshd session required pam_permit.so 736 73720001031: 738 cvs updated to 1.11. 739 74020001020: 741 The random device needs more entropy, so you need to make sure 742 that you've run mergemaster to get a /etc/rc which will seed 743 /dev/random. If you don't and the system hangs after ldconfig, 744 then banging on the keyboard randomly until it unhangs is one 745 workaround. 746 74720001010: 748 ****************************** WARNING ****************************** 749 Sendmail has been updated. 750 ****************************** WARNING ****************************** 751 o mail.local(8) is no longer installed as a set-user-id binary. 752 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 753 is set. 754 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 755 commands. 756 o Now using sendmail's version of vacation(1). 757 o The sendmail cf building tools (contrib/sendmail/cf) are installed 758 in /usr/share/sendmail/cf. 759 o sendmail.cw changed to local-host-names 760 761 More details can be found at 762 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 763 76420001009: 765 The ports tree's new layout is in place. Be sure to update 766 your entire ports tree, or you will have problems. 767 76820001006: 769 The perl build procedure no longer installs miniperl, nor uses 770 the installed miniperl. It is recommended that you delete 771 /usr/bin/miniperl. 772 77320001005: 774 This weekend the ports tree will be updated to a new layout. 775 It will be in an inconsistent state until noted in the UPDATING 776 file, or with asami-san's message to the relevant mailing 777 lists. With this new layout, you'll need to update the whole 778 tree for anything to work. 779 78020000928: 781 There was a change in the passwd format. Need more information. 782 78320000916: 784 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 785 place. Please update boot loader (not the boot blocks) at the 786 same time as your kernel. 787 78820000914: 789 The new pmtimer device is necessary for laptops. Failure to 790 include the device will cause suspended laptops losing time 791 when they resume. Include 792 device pmtimer 793 in your config file and 794 hint.pmtimer.0.at="isa" 795 to your /boot/device.hints file. 796 79720000911: 798 The random device has been turned into a (pseudo-)device, 799 rather than an option. The supplied kernel config files have 800 been updated. You will need to do something similar in your 801 own kernel config file. 802 Remove: 803 options RANDOMDEV 804 Add: 805 device random 806 If you prefer to load the loadable module, you need to do 807 nothing. 808 80920000909: 810 The random device module has been renamed from randomdev.ko to 811 random.ko. You will need to edit your /boot/loader.conf to 812 reflect this if you load this module at boot time. 813 The line should read: 814 random_load="YES" 815 81620000907: 817 The SMPNG commit has happened. It should work, but if it 818 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 819 to be a variety of minor issues. Please see 20000905 to make 820 sure you don't have model loading problems which might at 821 first blush appear related to SMP. 822 82320000906: 824 nsswitch has been imported from NetBSD. Among other things, 825 this means that /etc/host.conf is no longer used. See 826 nsswitch.conf(5) instead. Note that at boot time rc.network 827 will attempt to produce a new nsswitch.conf file for you if you 828 don't have one, and you have host.conf. 829 83020000905: 831 The ucred structure changed size. This breaks the interface 832 that mountd uses. Trying to use an older mountd with a newer 833 kernel guarantees a panic. This means that you need to use 834 kernels newer than today only with matching mountd, but you 835 needed to do that anyway with the boot loader changes. 836 83720000905: 838 The boot loader has been updated. The new default kernel is 839 now /boot/kernel/kernel.ko. The new default module location 840 is /boot/kernel. 841 842 You *MUST* upgrade your boot loader and kernel at the same time. 843 The easiest way to do this is to do the buildworld/buildkernel/ 844 installkernel/installworld dance. 845 846 Furthermore, you are urged to delete your old /modules directory 847 before booting the new kernel, since kldload will find stale 848 modules in that directory instead of finding them in the correct 849 path, /boot/kernel. The most common complaint that this cures 850 is that the linux module crashes your machine after the update. 851 852 if [ ! -d /boot/kernel.old ]; then 853 mv /modules.old /boot/kernel.old 854 chflags noschg /kernel.old 855 mv /kernel.old /boot/kernel.old/kernel.ko 856 chflags schg /boot/kernel.old/kernel.ko 857 fi 858 85920000904: 860 A new issue with the sendmail upgrade has come to light. 861 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 862 incorrectly install the default aliases in /etc/mail rather than 863 move the old one from /etc. So you'll need to manually move the 864 file, create a symbolic link, remove the old /etc/aliases.db and 865 run newaliases. For safety sake, you should stop sendmail 866 while doing this and run the upgrade when locally sourced email 867 is not likely to be generated. 868 86920000825: 870 /boot/device.hints is now required for installkernel to 871 succeed. You should copy GENERIC.hints for your architecture 872 into /boot/device.hints. If and only if you compile hints 873 into your kernel, then this file may be empty. Please note, 874 if you have an empty or missing /boot/device.hints file and 875 you neglected to compile hints into your kernel, no boot 876 messages will appear after the boot loader tries to start the 877 kernel. 878 87920000821: 880 If you do NOT have ``options RANDOMDEV'' in your kernel and 881 you DO want the random device then add randomdev_load="YES" to 882 /boot/loader.conf. 883 88420000812: 885 suidperl is now always built and installed on the system, but 886 with permissions of 511. If you have applications that use 887 this program, you are now required to add ENABLE_SUIDPERL=true 888 to /etc/make.conf. If you forget to do this, 889 chmod 4511 /usr/bin/suidperl 890 will fix this until the next build. 891 89220000812: 893 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 894 visible changes that may immediately affect your configuration 895 include: 896 - New default file locations from src/contrib/sendmail/cf/README 897 - newaliases limited to root and trusted users 898 - MSA port (587) turned on by default 899 - New queue file naming system so can't go from 8.11 -> 8.9 900 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 901 - FEATURE(`nullclient') is more full featured 902 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 903 - mail.local FreeBSD-only -b option changed to -B 904 - See src/contrib/sendmail/RELEASE_NOTES for more info 905 90620000810: 907 suidperl (aka sperl) is no longer build by default. You must 908 specifically define BUILD_SUIDPERL to "true" for it to be build. 909 Furthermore, we recommend that you remove /usr/bin/sperl* and 910 /usr/bin/suidperl files from your system unless you have a 911 specific use for it. 912 91320000729: 914 Networking defaults have been tightened. Anybody upgrading 915 /etc/defaults/rc.conf needs to add the following lines to 916 /etc/rc.conf if they want to have the same setup 917 afterwards (unless the variables already are set, of course): 918 # Enable network daemons for user convenience. 919 inetd_enable="YES" 920 portmap_enable="YES" 921 sendmail_enable="YES" 922 92320000728: 924 If you have null_load="YES" in your /boot/loader.conf, you 925 will need to change that to nullfs_load="YES". 926 92720000728: 928 The "installkernel" target has changed slightly. Now even if 929 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 930 it will install the MYKERNEL file (built with the buildkernel 931 target) as /kernel rather than /MYKERNEL. Those who have 932 updated their /boot/loader.conf files to point to /MYKERNEL 933 should remove that entry or perform manual rename of /kernel 934 to /MYKERNEL. 935 93620000711: 937 If you use CVSUP or CTM to get CVS trees, AND you used to get 938 the old crypto files from internat.freebsd.org AND you check 939 out files from the CVS tree with the cvs command, please read 940 http://people.freebsd.org/~imp/internat.txt 941 for details on potential problems that you might have and how 942 to get around them. 943 944 If you are merely a mirror, or don't answer yes to each of the 945 clauses above, you needn't worry. 946 94720000711: 948 /etc/security has been updated to print the inode number of 949 setuid programs that have changed. You will see a large spike 950 in the number of changed programs the first time when you run 951 mergemaster to get a new /etc/security. 952 95320000710: 954 /dev/random now has good entropy collection (from the keyboard 955 and sysmouse drivers). Please ensure that either `options 956 RANDOMDEV' is present in your kernel config file or that 957 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 958 not have the /dev/random driver, OpenSSL (and consequently 959 lots of crypto tools (like SSH)) will fail with strange 960 errors. (see below, 20000624). 961 962 FreeBSD-current is safe again to run Crypto. 963 96420000709: 965 phk made the malloc default options AJ. This may slow things 966 down and uncover other latent bugs in the code. If you need to 967 run at full speed, you can disable this by doing the following: 968 ln -s aj /etc/malloc.conf 969 97020000706: 971 libftpio's version was accidentally bumped a few days ago. This 972 has been corrected. You may need to remove /usr/lib/libftpio.so.6 973 before doing your next buildworld/installworld pair. It certainly 974 won't hurt to remove it before the update procedure. It will 975 break fetch until a new one is built, but ftp can be used in the 976 interim if needed. 977 97820000705: 979 The crypto packages have changed for the cvsup. This has been done 980 in a backward compatible way, but the old packages will go away at 981 some point in the future. Look at /usr/share/examples/cvsup for 982 details. 983 98420000704: 985 With the new sys/modules/sound/drivers/*, you will need to 986 set SYSDIR until you do an installworld after July 7th. 987 98820000704: 989 rc.shutdown and rc will now call the rc.d scripts with start 990 or stop. This may cause some harmless warnings from older 991 rc.d scripts that haven't been updated. 992 99320000630: 994 The libfetch based version of fetch has gone into the tree. 995 Minor problems may result on some of the less popular sites, 996 which should be reported to des@freebsd.org. 997 99820000625: 999 From approximately this date forward, one must have the crypto 1000 system installed in order to build the system and kernel. 1001 While not technically strictly true, one should treat it as 1002 required and grab the crypto bits. If you are grabbing CVS 1003 trees, src-all and cvs-crypto should be treated as if they 1004 were required. You should check with the latest collections 1005 to make sure that these haven't changed. 1006 100720000624: 1008 Mark Murray just committed the first parts of a cleanup of 1009 /dev/zero, et al. This is also cleaning up /dev/random. 1010 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1011 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1012 until Mark can merge in the fixes to this work in progress. 1013 openssh and openssl should not be used to generate keys from this 1014 date to the completion of the work. 1015 1016 If you must operate at this reduced level of security, add ' 1017 options RANDOMDEV' to your kernel or modload the randomdev 1018 module. You may also need to copy a new MAKEDEV to /dev and 1019 recreate the random and urandom devices. 1020 102120000622: 1022 The license on the softupdates is now a standard 2 clause 1023 BSD license. You may need to remove your symbolic links 1024 that used to be required when updating. 1025 102620000621: 1027 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1028 the config file update procedure. 1029 http://people.freebsd.org/~imp/config-upd.html 1030 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1031 isn't buildable. However, you can generate a LINT file: 1032 cd /sys/<ARCH>/conf && make LINT 1033 103420000620: 1035 Binutils 2.10 have hit the tree, or will shortly. As soon 1036 as they do, the problem noted in 20000522 will be resolved and 1037 that workaround will no longer be required. 1038 103920000615: 1040 phk removed the compatibility creation of wd devices in the 1041 ad driver. If you haven't done so already, you must update 1042 your fstab, etc to use the ad devices instead of the wd 1043 devices. 1044 1045 In addition, you'll need to update your boot blocks to a 1046 more modern version, if you haven't already done so. Modern 1047 here means 4.0 release or newer (although older releases 1048 may work). 1049 105020000612: 1051 Peter took an axe to config(8). Be sure that you read his mail 1052 on the topic before even thinking about updating. You will 1053 need to create a /boot/device.hints or add a hints directive 1054 to your config file to compile them in statically. The format 1055 of the config file has changed as well. Please see GENERIC or 1056 NEWCARD for examples of the new format. 1057 1058 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1059 says that it has been fixed, assume that must use the hints mechanism 1060 in the loader if you need to use a machine with very old ISA cards 1061 in it. 1062 106320000522: 1064 A new set of binutils went into the tree today. Anybody 1065 building a kernel after this point is advised that they need 1066 to rebuild their binutils (or better yet do a 1067 buildworld/installworld) before building a new kernel. 1068 1069 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1070 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1071 is recommended that you don't set this option until the problem 1072 is resolved. 1073 107420000513: 1075 The ethernet drivers were all updated to clean up the BPF handling. 1076 107720000510: 1078 The problems with boot blocks on the alphas have been corrected. 1079 This will require some care in updating alphas. A new libstand 1080 is requires for the boot blocks to build properly. 1081 108220000503: 1083 Recompile all kld modules. Proper version dependency info 1084 is now available. 1085 108620000502: 1087 Modules have been disconnected from the buildworld tree and 1088 connected to the kernel building instead. 1089 109020000427: 1091 You may need to build gperf 1092 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1093 when upgrading from 4.0 -> current. The build system now uses 1094 an option only in -current. 1095 109620000417: 1097 The method that we brand ELF binaries has changed to be more 1098 acceptable to the binutils maintainers. You will need to 1099 rebrand your ELF binaries that aren't native. One problem 1100 binary is the Linux ldconfig. After your make world, but 1101 before you reboot, you'll need to issue: 1102 brandelf -t Linux /compat/linux/sbin/ldconfig 1103 if you have Linux compatibility enabled on your machine. 1104 110520000320: 1106 If you have really bad/marginal IDE drives, you may find they 1107 don't work well. Use pio mode instead. The easiest way to 1108 cope if you have a problem combination is to add: 1109 /sbin/sysctl hw.ata.ata_dma=0 1110 to the start of /etc/rc.conf. 1111 111220000319: 1113 The ISA and PCI compatibility shims have been connected to the 1114 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1115 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1116 include the appropriate option in your kernel config. Drivers 1117 using the shims should be updated or they won't ship with 1118 5.0-RELEASE, targeted for 2001. 1119 112020000318: 1121 We've entered the traditional post release dumping party. 1122 Large kernel changes are being committed and are in the 1123 works. It is important to keep the systems' klds and kernel 1124 in sync as kernel interfaces and structures are changing. 1125 Before reporting kernel panics, make sure that all modules 1126 that you are loading are up to date. 1127 112820000315: 1129 If you are upgrading from an older version of FreeBSD, you 1130 need to update your boot blocks as well. 'disklabel -B ad0' 1131 will do the trick. This isn't critical until you remove your 1132 wd device entries in /dev, at which point your system will not 1133 boot. 1134 113520000315: 1136 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1137 to upgrade to 4.0 from 3.x. 1138 1139COMMON ITEMS: 1140 1141 General Notes 1142 ------------- 1143 Avoid using make -j when upgrading. From time to time in the 1144 past there have been problems using -j with buildworld and/or 1145 installworld. This is especially true when upgrading between 1146 "distant" versions (eg one that cross a major release boundary 1147 or several minor releases, or when several months have passed 1148 on the -current branch). 1149 1150 Sometimes, obscure build problems are the result of environment 1151 poisoning. This can happen because the make utility reads its 1152 environment when searching for values for global variables. 1153 To run your build attempts in an "environmental clean room", 1154 prefix all make commands with 'env -i '. See the env(1) manual 1155 page for more details. 1156 1157 To build a kernel 1158 ----------------- 1159 If you are updating from a prior version of FreeBSD (even one just 1160 a few days old), you should follow this procedure. With a 1161 /usr/obj tree with a fresh buildworld, 1162 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1163 make installkernel KERNCONF=YOUR_KERNEL_HERE 1164 1165 To just build a kernel when you know that it won't mess you up 1166 -------------------------------------------------------------- 1167 cd src/sys/{i386,alpha}/conf 1168 config KERNEL_NAME_HERE 1169 cd ../../compile/KERNEL_NAME_HERE 1170 make depend 1171 make 1172 make install 1173 1174 If this fails, go to the "To build a kernel" section. 1175 1176 To rebuild everything and install it on the current system. 1177 ----------------------------------------------------------- 1178 # Note: sometimes if you are running current you gotta do more than 1179 # is listed here if you are upgrading from a really old current. 1180 1181 <make sure you have good level 0 dumps> 1182 <maybe fix /etc/fstab> [7] 1183 make buildworld 1184 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1185 make installkernel KERNCONF=YOUR_KERNEL_HERE 1186 [1] 1187 <reboot in single user> [3] 1188 mergemaster -p [5] 1189 make installworld 1190 mergemaster [4] 1191 <reboot> 1192 1193 1194 To cross-install current onto a separate partition 1195 -------------------------------------------------- 1196 # In this approach we use a separate partition to hold 1197 # current's root, 'usr', and 'var' directories. A partition 1198 # holding "/", "/usr" and "/var" should be about 2GB in 1199 # size. 1200 1201 <make sure you have good level 0 dumps> 1202 <boot into -stable> 1203 make buildworld 1204 <maybe newfs current's root partition> 1205 <mount current's root partition on directory ${CURRENT_ROOT}> 1206 make installworld DESTDIR=${CURRENT_ROOT} 1207 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1208 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \ 1209 ${CURRENT_ROOT}/boot/device.hints # as needed 1210 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1211 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1212 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1213 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1214 <reboot into current> 1215 <do a "native" rebuild/install as described in the previous section> 1216 <maybe install compatibility libraries from /usr/src/lib/compat> 1217 <reboot> 1218 1219 1220 To upgrade in-place from 4.x-stable to current 1221 ---------------------------------------------- 1222 # 5.x uses more space than 4.x. Also, the location of kernel 1223 # modules has changed. If you are installing 5.0 onto a 4.x 1224 # system, you'll need about 30MB of free disk space on your / 1225 # partition. If you have less than this, you may encounter difficult 1226 # to back out of problems with this procedure. If /tmp is on 1227 # the / partition, you may want to completely remove all its content 1228 # before upgrading, as this can be a common source of shortage of 1229 # space on /. 1230 1231 <make sure you have good level 0 dumps> 1232 <maybe fix /etc/fstab> [7] 1233 make buildworld [9] 1234 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1235 cp src/sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1236 make installkernel KERNCONF=YOUR_KERNEL_HERE 1237 cd src/sys/boot ; make install [6] 1238 [1] 1239 <reboot in single user> [3] 1240 mergemaster -p [5] 1241 rm -rf /usr/include/g++ 1242 make installworld 1243 mergemaster [4] 1244 <reboot> 1245 1246 Make sure that you've read the UPDATING file to understand the 1247 tweaks to various things you need. At this point in the life 1248 cycle of current, things change often and you are on your own 1249 to cope. The defaults can also change, so please read ALL of 1250 the UPDATING entries. 1251 1252 Also, if you are tracking -current, you must be subscribed to 1253 freebsd-current@freebsd.org. Make sure that before you update 1254 your sources that you have read and understood all the recent 1255 messages there. If in doubt, please track -stable which has 1256 much fewer pitfalls. 1257 1258 [1] If you have third party modules, such as vmware, you 1259 should disable them at this point so they don't crash your 1260 system on reboot. 1261 1262 [2] If you have legacy ISA devices, you may need to create 1263 your own device.hints to reflect your unique hardware 1264 configuration. 1265 1266 [3] From the bootblocks, boot -s, and then do 1267 fsck -p 1268 mount -u / 1269 mount -a 1270 cd /usr/src 1271 adjkerntz -i # if CMOS is wall time 1272 Also, when doing a major release upgrade, it is required that 1273 you boot into single user mode to do the installworld. 1274 For the 4.x -> 5.0 upgrade, you will also see many messages about 1275 needing to recompile your userland. These are harmless and can 1276 be ignored while you proceed to the next step. 1277 1278 [4] Note: This step is non-optional. Failure to do this step 1279 can result in a significant reduction in the functionality of the 1280 system. Attempting to do it by hand is not recommended and those 1281 that pursue this avenue should read this file carefully, as well 1282 as the archives of freebsd-current and freebsd-hackers mailing lists 1283 for potential gotchas. 1284 1285 [5] Usually this step is a noop. However, from time to time 1286 you may need to do this if you get unknown user in the following 1287 step. It never hurts to do it all the time. You may need to 1288 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1289 install) after the buildworld before this step if you last updated 1290 from current before 20020224 or from -stable before 20020408. 1291 1292 [6] 4.x boot loader can be used to boot a 5.x system, however 1293 it is difficult to do that at best. If you wish to try, then 1294 you should interrupt the boot and at the ok prompt type: 1295 ok unload 1296 ok boot /boot/kernel/kernel 1297 If this fails to work, you must install a new boot loader as 1298 described here. 1299 1300 [7] Before you upgrade, please make sure that you are not using 1301 compatibility slices. These are device names of the form, on i386 1302 and other architectures that use MBR slicing, /dev/ad0a without the 1303 actual slice name. Chances are excellent that these will break. 1304 You generally must update these entries to use the post FreeBSD 1305 2.x form of /dev/ad0s1a. 1306 1307 [8] In order to have a kernel that can run the 4.x binaries 1308 needed to do an installworld, you must include the COMPAT_FREEBSD4 1309 option in your kernel. Failure to do so may leave you with a system 1310 that is hard to boot to recover. 1311 1312 [9] When checking out sources, you must include the -P flag to have 1313 cvs prune empty directories. 1314FORMAT: 1315 1316This file contains a list, in reverse chronological order, of major 1317breakages in tracking -current. Not all things will be listed here, 1318and it only starts on March 15, 2000. Updating files can found in 1319previous releases if your system is older than this. 1320 1321Copyright information: 1322 1323Copyright 1998, 2002 M. Warner Losh.
