UPDATING revision 117463
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 2020030711: 21 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 22 across this point. Further, it might be a good idea to remove 23 /usr/obj. 24 2520030613: [retrospective] 26 There was a small window in which sed(1) was broken. If you 27 happen to have sed(1) installed during that window, which is 28 evidenced by an inability to build world with the failure 29 given below, you need to manually build and install sed(1) 30 (and only sed(1)) before doing anything else. This is a one- 31 time snafu. Typical failure mode: 32 33 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 34 targmatch.h:7:1: null character(s) ignored 35 targmatch.h:12:1: null character(s) ignored 36 targmatch.h:16:1: null character(s) ignored 37 : 38 39 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 40 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 41 usr.bin/sed/process.c). 42 4320030610: 44 Remove deprecated locale names and transition period code 45 for them, finishing switching to the new scheme. Check your 46 LANG environment variable. 47 4820030609: 49 CCD has been changed to be a fully GEOMified class. Kernel 50 and ccdconfig(8) needs to be in sync, this is particularly 51 important to remember beforehand if your source tree is on 52 a ccd device. Consider making a copy of the old ccdconfig 53 into /boot/kernel.good or wherever you keep your backup 54 kernel. 55 5620030505: 57 Kerberos 5 (Heimdal) is now built by default. Setting 58 MAKE_KERBEROS5 no longer has any effect. If you do NOT 59 want the "base" Kerberos 5, you need to set NO_KERBEROS. 60 6120030502: 62 groff has been updated. If you try to do a buildworld and 63 get an infinite loop in troff, update to May 4th or newer. If you 64 have a newer kernel than userland, you may need to set the OSRELDATE 65 to 500110 in your environment before starting a buildworld. 66 6720030501: 68 The old rc system has been removed. Please report any problems 69 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 70 Your personal versions of these files will not be removed, so you can 71 continue to use them. However, you should take great care when updating, 72 especially when using mergemaster, since the compatibility code that 73 utilizes these old scripts has also been removed. 74 7520030423: 76 A bug has been fixed in /dev/devctl which would cause devd 77 to hang on boot, were it not for a workaround in devd. The 78 work around in devd will be removed around 20030507. You 79 have until then to upgrade your kernel before updating 80 userland. In general, you should have a userland and 81 kernel that's in sync with each other. However, given the 82 effects of this bug (hang on boot when starting devd), some 83 allowances are made. 84 8520030329: 86 Alphas with libc from between 20030312 and 20030329 exhibit 87 floating point exceptions (FPEs), most notably in awk(1) 88 while upgrading the system through a buildworld. 89 90 So, to successfully upgrade your Alpha, you must either 91 downgrade your libc.so to a pre-20030312 version, or update 92 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 93 to CFLAGS, then forcibly rebuild and install libc: 94 95 cd /usr/src/lib/libc && \ 96 make cleandir && make obj && \ 97 make -DNOMAN -DNOPROFILE all && \ 98 make -DNOMAN -DNOPROFILE install 99 10020030208: 101 sendmail 8.12.7 has been imported. It has one important 102 change for IPv6 users. The default submit.mc now uses 103 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 104 used to connect to the MTA. Users on IPv6-only machines 105 will need to edit /etc/mail/submit.mc appropriately. 106 10720030128: 108 NODEVFS option has been removed and DEVFS thereby made standard. 109 This makes all references to MAKEDEV obsolete, and they should 110 be removed when convenient. 111 11220030126: 113 The name of the device for the ofw console has changed, sparc64 users 114 must run mergemaster to update their installed /etc/ttys. 115 11620030125: 117 The scheduler framework has grown a second scheduler and consequently 118 you must specify one and only one scheduler in your kernel config. 119 The cvs config files have been updated to use the old scheduler 120 which may be selected via 'options SCHED_4BSD'. If you would like 121 to try the new, much more experimental, scheduler please try 122 'options SCHED_ULE' and contribute to the arch@ discussion. 123 12420030115: 125 A new version of the wi driver has been imported into the tree. 126 One now must have device wlan in the config file for it to operate 127 properly. 128 129 In addition, there have been some changes to how wi devices are 130 configured for point to point links to bring it more in line 131 with the former way of doing things, as well as compatibility 132 with NetBSD. 133 13420021222: 135 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 136 used an incompatible form of ABI for returning structures and unions 137 which FreeBSD's GCC maintainers were not aware of relative to previous 138 versions of FreeBSD. We have gone back to the ABI for now, and any 139 code compiled which is required to interoperate with other code (not 140 built at the same time) returning structs or unions should be 141 rebuilt. 142 14320021216: 144 A name change in /etc/netconfig has been reverted to stay 145 compatible with suns TIRPC and also with NetBSD. You need 146 to run mergemaster after make world. A new libc does still work 147 with an outdated /etc/netconfig for some time, but you'll get 148 a warning. This warning will be removed in 20030301. 149 15020021202: 151 The recent binutils upgrade marks a kernel flag day on 152 sparc64: modules built with the old binutils will not work 153 with new kernels and vice versa. Mismatches will result in 154 panics. Make sure your kernel and modules are in sync. 155 15620021029: 157 The value of IPPROTO_DIVERT has changed. Make sure to keep 158 your kernel, netstat, natd and any third-party DIVERT 159 consumers in sync. 160 16120021024: 162 Old, compatibility slices have been removed in GEOM kernels. 163 This means that you will have to update your /etc/fstab to 164 not use disk devices of the form /dev/ad0a. Instead, you 165 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 166 partition really is on. The old device names have gone 167 away, so if you use them anywhere else, you must also adjust 168 those uses. (This doesn't affect the disks formatted in 169 the ``dangerously-dedicated'' mode.) 170 17120021023: 172 Alphas with kernels from between 20020830 and 20021023 and/or 173 rtld (ld-elf.so.1) older than 20021023 may experience problems 174 with groff while doing a buildworld (kernel: "out of memory", 175 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 176 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 177 178 So, to successfully upgrade your Alpha, you must either 179 upgrade your kernel and rtld first (which might be a bit 180 tricky), or avoid running the bootstrapped groff during the 181 "transitional" buildworld. To avoid running groff during the 182 transitional upgrade run make buildworld with -DNOMAN, 183 -DNO_SHAREDOCS, and -DNO_LPR. 184 18520020831: 186 gcc has been upgraded to 3.2. It is not all binary compatible 187 with earlier versions of gcc for c++ programs. All c++ 188 programs and libraries need to be recompiled. 189 190 Also, if you encounter g++ issues, rm /usr/include/g++/* before 191 doing an installworld to make sure that stale files are removed. 192 19320020827: 194 Our /etc/termcap now has all the entries from the XFree86 xterm 195 almost unchanged. This means xterm now supports color by default. 196 If you used TERM=xterm-color in the past you now should use 197 TERM=xterm. (xterm-color will lead to benign warnings). 198 19920020815: 200 A "bug" in gcc(1) that was hiding warning in system headers was 201 fixed. It's probably time to add -DNO_WERROR to your make line 202 again. 203 20420020729: 205 COPY is being deprecated. The 20010530 change was reverted, as 206 it causes far more pain than was expected, and to always compare 207 before installing, please use INSTALL="install -C" again. The 208 -C option is now silently ignored when used with the -d option. 209 21020020702: 211 Problems with libc_r clients like KDE and GNOME have been resolved. 212 There are still some minor problems with some signals but the 213 system is stable enough for general use again. SMP is less so than UP 214 but each can successfully complete multiple buildworlds. 215 Libkvm needs to be recompiled due to KSE. 216 21720020701: 218 Now would be a bad time to upgrade. Something in or near the 219 KSE commit totally broke programs using libc_r like KDE and 220 GNOME. 221 22220020511: 223 The k5su utility installed as part of Kerberos 5 is no longer 224 installed with the set-user-ID bit set by default. Add 225 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 226 with the set-user-ID bit set. 227 22820020510: 229 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 230 Unfortunately our native GDB (at version 4.18) does not understand 231 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 232 generated debugging information for our native GDB. 233 23420020510: 235 Due to the way CVS works, it may not properly update src/contrib/gcc 236 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 237 and then do a cvs update. 238 23920020421: 240 When exec'ing set[ug]id executables, the kernel now ensures that the 241 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 242 24320020404: 244 New sendmail startup scripts have been installed to make it 245 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 246 variable sendmail_enable to "NO" no longer prevents any sendmail 247 daemons from starting. Instead, either set sendmail_enable to 248 "NONE" or change mta_start_script to a script for starting 249 an alternative MTA. Setting mta_start_script to "" will 250 also prevent any MTA from being started at boot. 251 25220020403: 253 UCONSOLE is no longer a valid kernel option. 254 25520020315: 256 FreeBSD 5.0 DP-1 was basically branched today. 257 25820020225: 259 Warnings are now errors in the kernel. Unless you are a developer, 260 you should add -DNO_WERROR to your make line. 261 26220020217: 263 sendmail 8.12.2 has been imported. The sendmail binary is no 264 longer a set-user-ID root binary and the infrastructure to support 265 command line mail submission has changed. Be sure to run 266 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 267 and /etc/mail) and read /etc/mail/README for more details. 268 269 Due to the import of sendmail 8.12.2, a new user and group are 270 required in order for sendmail to run as a set-group-ID 271 binary. A 'make installworld' will use the new user and group 272 to set the owner and group of /var/spool/clientmqueue and will 273 fail if the new user and group do not exist. The 'smmsp' user 274 and group must be merged from src/etc/group and 275 src/etc/master.passwd before using 'make installworld'. 276 'mergemaster -p' will do this. You may need to install 277 mergemaster before this will work if you are updating from a 278 very old version of current. The updating recipe has changed 279 as of this date. 280 28120020112: 282 The preferred configuration method for PAM is now /etc/pam.d/ 283 rather than /etc/pam.conf. If you have an unmodified 284 pam.conf, just delete it after your next mergemaster run. If 285 you have local modifications, you can use 286 /usr/src/etc/pam.d/convert.pl to incorporate them into your 287 /etc/pam.d. 288 289 Please see the following url for more details: 290http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 29120011229: 292 If anyone here is already using the new rc.conf(5) variable 293 networkfs_types, please note that it has changed 294http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 295 29620011220: 297 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 298 started out its life in the ISDN4BSD project as an offspring 299 from sys/net/if_spppsubr.c, which eventually got a life of its 300 own. All the accumulated features and bugfixes of the i4b 301 version have now been merged back into the base system's 302 version now. The only user-visible change resulting from this 303 is that i4b's sppp(4) interfaces are to be managed with 304 spppcontrol(8) again, since ispppcontrol(8) has been retired 305 as well. (There has never been rc file support for 306 ispppcontrol in -current, but only in -stable. That will be 307 reverted by the time the changes are MFCed.) 308 30920011215: 310 The fdc(4) driver has been updated and now automatically 311 recognizes media in `standard' formats (like 1440 KB and 312 720 KB for a 3.5" high-density drive) when accessing the 313 default device node (e. g. /dev/fd0). The old variety of 314 floppy device nodes /dev/fd*.* is no longer present by 315 default, devices can be created (in DEVFS) on demand. They 316 will need to be customized then for `odd' densities using 317 fdcontrol(8). 318 31920011209: 320 The bugs in procfs' debugging support code have been fixed, 321 and truss(1) now works again. 322 32320011207: 324 Daily security checks have been split out to use the periodic(8) 325 scripts. Some change in configuration may be necessary. Please 326 see 327http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 328 for details. 329 33020011204: 331 sos added VCD/SVCD support to ata driver and that needs the 332 kernel and burncd to be in sync. 333 33420011203: 335 The procfs pseudo-filesystem has now been converted to use the 336 pseudofs framework. If you have 'options PROCFS' in your 337 kernel config, you'll need to add 'options PSEUDOFS' if it's 338 not there already. 339 340 This change temporarily breaks truss(1); use ktrace(1) instead 341 until the issue has been resolved. 342 34320011202: 344 A security hole in OpenSSH involving `UseLogin yes' has been 345 patched. 346 34720011126: 348 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 349 after this date. You need to do this only once. 350 35120011103: 352 Most of the awk issues have been resolved. Some rough 353 edges may be left, but for the most part things should be 354 back to "normal." For CURRENT's usual definition of "normal." 355 35620011030: 357 Awk has been upgraded to the one true awk from bell labs. Expect 358 choppy waves in the upgrade process. 359 36020011030: 361 The asr driver problem has been resolved. 362 36320011027: 364 Due to changes in other parts of the system, the asr driver 365 now causes the system to panic on boot. Do not use it pending 366 correction. Comment it out of any kernel config file that you 367 try to use from this date forward. 368 36920011025: 370 When crossbuilding, use TARGET=xxx where you used to use 371 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 372 unless you are changing both of them. To cross build pc98 on 373 an alpha, for example, you need to set TARGET=pc98 and 374 TARGET_ARCH=i386. 375 37620011001: 377 The kernel interface that burncd depends on has changed. 378 You must recompile both the kernel and userland applications 379 at the same time. 380 38120010929: 382 When crossbuilding, please set TARGET_ARCH rather than 383 MACHINE_ARCH to indicate the target. In the future, one will 384 set TARGET_MACHINE where you set MACHINE now. At the moment, 385 setting MACHINE alone for same MACHINE_ARCH machines works 386 (eg, you can build pc98 on an i386 machine and vice versa). 387 38820010927: 389 Some weird problems result from using ACPI on some machines. 390 To disable ACPI you can add 391 hint.acpi.0.disabled="1" 392 to /boot/loader.conf (or by putting set X=Y at the boot 393 loader "ok" prompt). 394 395 Alternatively, you can remove it from /boot/kernel/acpi.ko 396 or use the MODULES_OVERRIDE function in your kernel config 397 file and not list acpi in that list. 398 39920010924: 400 The buildworld has been fixed. You may need to install 401 the 4.x compatibility libraries for some old binaries 402 to work. Add COMPAT4X=true to your /etc/make.conf to 403 get them installed on every installworld, or execute the 404 following to get them installed only once: 405 cd src/lib/compat/compat4x.<arch> 406 make all install 407 You will see ``__stdoutp undefined'' until you do this. 408 40920010919: 410 There's a bug in the world build process. The cross-tools 411 are build with the NEW headers, but the OLD libc.a. This 412 leads to all kinds of problems with the new libc. A temporary 413 workaround is to add 414 CFLAGS="-O -pipe -D_OLD_STDIO" 415 before building world when upgrading from 4.x to current. This 416 can be removed afterwards. 417 418 A proper fix to the buildworld target is needed. 419 42020010918: 421 Peter has committed his new kthread nfs client/server code. 422 NFS may be unstable after this date. 423 42420010912: 425 KSE has hit the tree. Lots of things are now different in 426 the kernel. While a few problems were introduced in the 427 initial commit, most of the major ones have been found and 428 corrected. 429 43020010901: 431 In OLDCARD, CardBus bridges appear to be stable. The work 432 arounds described in the 20010604 entry are now no longer 433 necessary and will be ignored. Most insert/remove problems 434 have been rectified around this date. 435 43620010823: 437 named now runs as user bind and group bind rather than as 438 root. If named_enable is set to YES in /etc/rc.conf, ensure 439 that user bind is available in /etc/passwd (using vipw(8)) 440 and that group bind is available in /etc/group. Also make 441 sure that user or group bind has read (and not write) 442 permission for your name server configuration and that it 443 has read and write permission for your slave zone files and 444 directory. 445 446 If you wish to continue to run named as root (a less secure 447 alternative), add a line to /etc/rc.conf saying 448 449 named_flags= 450 45120010709: 452 The PAM libraries have had an API upgrade that is beyond 453 the ability of the shared library major number to handle. 454 It is manifested by PAM-using ports dumping core. The 455 solution is to rebuild those ports. 456 45720010628: 458 The kernel compile module has moved from src/sys/compile/FOO 459 to src/sys/${MACHINE}/compile/FOO. 460 46120010625: 462 The pccard modem issue from 20010613 has been corrected. 463 OLDCARD support is still a little weak in -current. slot 1 is 464 known not to work on some TI based cardbus bridges. Some 465 cardbus bridges do not properly detect insert/removal events. 466 IRQ configuration needs more safety belts. 467 46820010617: 469 Softupdates problems have been corrected. 470 47120010614: 472 Peter ripped out the linkerset support. You must, as always, 473 rerun config after you cvsup if you are using the traditional 474 kernel building methods. 475 47620010613: 477 pccard modems may not work with current after 20010604 date. Some 478 do, others result in panics. *MAKE*SURE* that you update your 479 config and /etc/rc.conf ala the 20010604 entry, or you will have 480 problems (this issue will be fixed, it just hasn't been yet). 481 48220010613: 483 SOFTUPDATES seem to be broken since the middle of May or so. Do not 484 use them in current. You can disable softupdates on all mounted 485 partitions, or remove SOFTUPDATES the kernel config file. 486 48720010612: 488 After Peter's commits to the hints code, people have been noticing 489 that certain devices are attached (or try to) twice. This is due 490 to having both static hints as well as a /boot/device.hints. To 491 work around this issue, please use only one or the other mechanism 492 until this bug is fixed. 493 494 Please note that a feature of config is that if you have config 495 file FOO and FOO.hints, it automatically adds FOO.hints to the 496 hints.c file, whether you want it to or not. 497 49820010610: 499 Locale names have changed to match other systems better. 500 50120010604: 502 pccard support for pci cards has been committed. You must change 503 your /etc/pccard.conf irq lines. It must match the irq used by 504 pcic device. Interrupt storms may result if you fail to do this. 505 Interrupt storms look a lot like a hang. 506 507 You must also install a new pccardd, otherwise you will get an 508 interrupt storm at card reset time (just after it tells you what 509 it is). 510 511 pccardd_flags="-I" is necessary for the time being. It tells pccardd 512 not to ask the kernel if the interrupt is really free or not before 513 using it. You can either change the /etc/pccard.conf irq lines to 514 match pcic, or add "-i X" to the pccardd_flags. 515 51620010530: 517 INSTALL=install -C is being deprecated. If you want to do this, 518 use COPY=-C instead. The former method will be supported for only 519 a limited time. If you see 520 521install: warning: the -d and -C options may not be specified together 522 523 in your makeworld, then you need to migrate towards using 524 COPY=-C. 525 52620010525: 527 It appears that vm is now stable enough to use again. However, 528 there may be other problems, so caution is still urged. alpha 529 definitely is in bad shape. 530 53120010521: 532 Minor repo damage has happened. This may cause problems 533 with cvsup of ports. If you get errors, please see 534 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 535 at the bottom for details on a workaround. The error message 536 is 537Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 538 53920010520: 540 Vm and/or swapping are busted on -current. Please be patient. 541 54220010519: 543 pccard has had much reorganizational work done to it over 544 the past few days. Everything should still work, but if 545 not, please contact imp@freebsd.org. 546 54720010517: 548 ata ioctl changed. Make sure to recompile both kernel and 549 userland at the same time. 550 55120010517: 552 New ncurses imported. 553 55420010512: 555 DEVFS is now opt out, not opt in. Barring major problems, this 556 will be the only way to go starting July 1. 557 55820010504: 559 OpenSSH has been updated to 2.9. Some defaults are different, 560 including RhostsRSAAuthentication, which changes from yes to no. 561 56220010502: 563 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 564 56520010501: 566 Building perl was broken at 02:25:25 PDT. 567 56820010430: 569 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 570 go back in the water. 571 57220010429: 573 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 574 this date, but before the correction date. 575 57620010423: 577 old fsck and new kernel interactions appear to have been fixed. 578 57920010411: 580 fsck and the kernel were changed to handle some optimizations 581 to directory layout. This breaks backward compatibility. 582 Update only if you understand that you must not use the old 583 fsck with the new kernel ever. 584 58520010330: 586 fsck has changed the meaning of the pass column in /etc/fstab. 587 Please see the cvs commit to fsck.8 or the fsck.8 man page for 588 details. It is unclear if changes to /etc/fstab are necessary. 589 59020010319: 591 portmap had changed name to rpcbind for maximum POLA in your 592 current world. /etc/hosts.{allow,deny} needs changes. nfs and 593 other rpc based programs that rely on portmapper will not work 594 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 595 59620010315: 597 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 598 and ATA_ENABLE_TAGS are no longer kernel options. They have 599 been replaced by tunables. See ata.4 for details. 600 60120010312: 602 The fxp driver was converted to use miibus. If you compile 603 fxp into your kernel statically, you will need to add miibus. 604 60520010312: 606 The wi device now defaults to BSS (infrastructure) mode 607 instead of ad-hoc. 608 60920010310: 610 /dev/urandom should be a symbolic link to /dev/random now. 611 Users of current not using DEVFS need to run MAKEDEV std. 612 ssh might not work if you don't. 613 61420010303: 615 The ed driver has been updated. It now allows mii attachments, 616 which means that you must include the miibus in your kernel if 617 you use the ed driver. 618 61920010220: 620 The problems with libc have been corrected. It is now mostly 621 safe to go back into the water. 622 62320010211: 624 The size of FILE was changed. This breaks upgrading. If 625 you must upgrade, be prepared for pain. It also breaks almost 626 all binaries that you've compiled on -current. You are warned 627 that before upgrading would be a good time to do a level 0 628 dump of your system. No, really, I mean it this time. 629 630 To get to the new system, you'll need to use the following 631 workaround. Hopefully this can be sorted out so that we 632 don't have to move this to the updating section. 633 634 To get around the installworld problem, do: 635 # cd /usr/src/usr.bin/sed 636 # make install 637 # cd /usr/src 638 # make installworld 639 If that doesn't work, then try: 640 # make -k installworld 641 # make installworld 642 64320010207: 644 DEVFS is now the default. If you use vinum, make sure that you 645 do not include devfs in your kernel as problems result. 646 64720010205: 648 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 649 Remove them from your config. 650 65120010122: 652 ****************************** WARNING ****************************** 653 buildkernel has been changed slightly 654 ****************************** WARNING ****************************** 655 KERNCONF replaces the variable KERNEL for buildkernel. You 656 should update your scripts and make.conf accordingly. 657 65820010119: 659 config has changed to allow DEV_FOO as a replacement for NFOO. 660 This requires a new config to build correctly. 661 66220010116: 663 The kernel option I386_CPU is now mutually exclusive with the 664 other cpu types. If you have an i386 system, be sure that it 665 only had this line. Remove it for all other configurations. 666 66720010110: 668 Changes to the kernel require it and burncd be in sync. 669 67020010102: 671 Everyone who has hw.sndunit set to something in 672 /etc/sysctl.conf, it is now hw.snd.unit. 673 67420010101: 675 ex and vi were broken by some changes to sys/queue.h. If you 676 have a bad vi, you will see make buildworld fail with a core 677 dump while building termcap. You can work around this problem 678 by adding -k to your make buildworld. This will cause the 679 build to complete and install a new vi. Once that's done, you 680 can rebuild again without the -k to pick up anything that 681 might have been ignored by the -k option. 682 683 Others have suggested that you can just rebuild libc if your 684 vi/ex is dynamically linked, but I've not received any reports 685 of this working. 686 68720001228: 688 There have been some changes to libcrypt in -current. The 689 libscrypt/libdescrypt symlink silliness is gone and the installed 690 libcrypt is fully functional. Be aware of this. 691 69220001218: 693 Linksys Fast Ethernet PCCARD cards supported by the ed driver 694 now require the addition of flag 0x80000 to their config line 695 in pccard.conf(5). This flag is not optional. These Linksys 696 cards will not be recognized without it. 697 69820001205: 699 Important new FreeBSD-version stuff: PAM support has been worked 700 in, partially from the "Unix" OpenSSH version. This requires 701 adding the following in pam.conf: 702 703 sshd auth sufficient pam_skey.so 704 sshd auth required pam_unix.so try_first_pass 705 sshd session required pam_permit.so 706 70720001031: 708 cvs updated to 1.11. 709 71020001020: 711 The random device needs more entropy, so you need to make sure 712 that you've run mergemaster to get a /etc/rc which will seed 713 /dev/random. If you don't and the system hangs after ldconfig, 714 then banging on the keyboard randomly until it unhangs is one 715 workaround. 716 71720001010: 718 ****************************** WARNING ****************************** 719 Sendmail has been updated. 720 ****************************** WARNING ****************************** 721 o mail.local(8) is no longer installed as a set-user-id binary. 722 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 723 is set. 724 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 725 commands. 726 o Now using sendmail's version of vacation(1). 727 o The sendmail cf building tools (contrib/sendmail/cf) are installed 728 in /usr/share/sendmail/cf. 729 o sendmail.cw changed to local-host-names 730 731 More details can be found at 732 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 733 73420001009: 735 The ports tree's new layout is in place. Be sure to update 736 your entire ports tree, or you will have problems. 737 73820001006: 739 The perl build procedure no longer installs miniperl, nor uses 740 the installed miniperl. It is recommended that you delete 741 /usr/bin/miniperl. 742 74320001005: 744 This weekend the ports tree will be updated to a new layout. 745 It will be in an inconsistent state until noted in the UPDATING 746 file, or with asami-san's message to the relevant mailing 747 lists. With this new layout, you'll need to update the whole 748 tree for anything to work. 749 75020000928: 751 There was a change in the passwd format. Need more information. 752 75320000916: 754 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 755 place. Please update boot loader (not the boot blocks) at the 756 same time as your kernel. 757 75820000914: 759 The new pmtimer device is necessary for laptops. Failure to 760 include the device will cause suspended laptops losing time 761 when they resume. Include 762 device pmtimer 763 in your config file and 764 hint.pmtimer.0.at="isa" 765 to your /boot/device.hints file. 766 76720000911: 768 The random device has been turned into a (pseudo-)device, 769 rather than an option. The supplied kernel config files have 770 been updated. You will need to do something similar in your 771 own kernel config file. 772 Remove: 773 options RANDOMDEV 774 Add: 775 device random 776 If you prefer to load the loadable module, you need to do 777 nothing. 778 77920000909: 780 The random device module has been renamed from randomdev.ko to 781 random.ko. You will need to edit your /boot/loader.conf to 782 reflect this if you load this module at boot time. 783 The line should read: 784 random_load="YES" 785 78620000907: 787 The SMPNG commit has happened. It should work, but if it 788 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 789 to be a variety of minor issues. Please see 20000905 to make 790 sure you don't have model loading problems which might at 791 first blush appear related to SMP. 792 79320000906: 794 nsswitch has been imported from NetBSD. Among other things, 795 this means that /etc/host.conf is no longer used. See 796 nsswitch.conf(5) instead. Note that at boot time rc.network 797 will attempt to produce a new nsswitch.conf file for you if you 798 don't have one, and you have host.conf. 799 80020000905: 801 The ucred structure changed size. This breaks the interface 802 that mountd uses. Trying to use an older mountd with a newer 803 kernel guarantees a panic. This means that you need to use 804 kernels newer than today only with matching mountd, but you 805 needed to do that anyway with the boot loader changes. 806 80720000905: 808 The boot loader has been updated. The new default kernel is 809 now /boot/kernel/kernel.ko. The new default module location 810 is /boot/kernel. 811 812 You *MUST* upgrade your boot loader and kernel at the same time. 813 The easiest way to do this is to do the buildworld/buildkernel/ 814 installkernel/installworld dance. 815 816 Furthermore, you are urged to delete your old /modules directory 817 before booting the new kernel, since kldload will find stale 818 modules in that directory instead of finding them in the correct 819 path, /boot/kernel. The most common complaint that this cures 820 is that the linux module crashes your machine after the update. 821 822 if [ ! -d /boot/kernel.old ]; then 823 mv /modules.old /boot/kernel.old 824 chflags noschg /kernel.old 825 mv /kernel.old /boot/kernel.old/kernel.ko 826 chflags schg /boot/kernel.old/kernel.ko 827 fi 828 82920000904: 830 A new issue with the sendmail upgrade has come to light. 831 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 832 incorrectly install the default aliases in /etc/mail rather than 833 move the old one from /etc. So you'll need to manually move the 834 file, create a symbolic link, remove the old /etc/aliases.db and 835 run newaliases. For safety sake, you should stop sendmail 836 while doing this and run the upgrade when locally sourced email 837 is not likely to be generated. 838 83920000825: 840 /boot/device.hints is now required for installkernel to 841 succeed. You should copy GENERIC.hints for your architecture 842 into /boot/device.hints. If and only if you compile hints 843 into your kernel, then this file may be empty. Please note, 844 if you have an empty or missing /boot/device.hints file and 845 you neglected to compile hints into your kernel, no boot 846 messages will appear after the boot loader tries to start the 847 kernel. 848 84920000821: 850 If you do NOT have ``options RANDOMDEV'' in your kernel and 851 you DO want the random device then add randomdev_load="YES" to 852 /boot/loader.conf. 853 85420000812: 855 suidperl is now always built and installed on the system, but 856 with permissions of 511. If you have applications that use 857 this program, you are now required to add ENABLE_SUIDPERL=true 858 to /etc/make.conf. If you forget to do this, 859 chmod 4511 /usr/bin/suidperl 860 will fix this until the next build. 861 86220000812: 863 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 864 visible changes that may immediately affect your configuration 865 include: 866 - New default file locations from src/contrib/sendmail/cf/README 867 - newaliases limited to root and trusted users 868 - MSA port (587) turned on by default 869 - New queue file naming system so can't go from 8.11 -> 8.9 870 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 871 - FEATURE(`nullclient') is more full featured 872 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 873 - mail.local FreeBSD-only -b option changed to -B 874 - See src/contrib/sendmail/RELEASE_NOTES for more info 875 87620000810: 877 suidperl (aka sperl) is no longer build by default. You must 878 specifically define BUILD_SUIDPERL to "true" for it to be build. 879 Furthermore, we recommend that you remove /usr/bin/sperl* and 880 /usr/bin/suidperl files from your system unless you have a 881 specific use for it. 882 88320000729: 884 Networking defaults have been tightened. Anybody upgrading 885 /etc/defaults/rc.conf needs to add the following lines to 886 /etc/rc.conf if they want to have the same setup 887 afterwards (unless the variables already are set, of course): 888 # Enable network daemons for user convenience. 889 inetd_enable="YES" 890 portmap_enable="YES" 891 sendmail_enable="YES" 892 89320000728: 894 If you have null_load="YES" in your /boot/loader.conf, you 895 will need to change that to nullfs_load="YES". 896 89720000728: 898 The "installkernel" target has changed slightly. Now even if 899 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 900 it will install the MYKERNEL file (built with the buildkernel 901 target) as /kernel rather than /MYKERNEL. Those who have 902 updated their /boot/loader.conf files to point to /MYKERNEL 903 should remove that entry or perform manual rename of /kernel 904 to /MYKERNEL. 905 90620000711: 907 If you use CVSUP or CTM to get CVS trees, AND you used to get 908 the old crypto files from internat.freebsd.org AND you check 909 out files from the CVS tree with the cvs command, please read 910 http://people.freebsd.org/~imp/internat.txt 911 for details on potential problems that you might have and how 912 to get around them. 913 914 If you are merely a mirror, or don't answer yes to each of the 915 clauses above, you needn't worry. 916 91720000711: 918 /etc/security has been updated to print the inode number of 919 setuid programs that have changed. You will see a large spike 920 in the number of changed programs the first time when you run 921 mergemaster to get a new /etc/security. 922 92320000710: 924 /dev/random now has good entropy collection (from the keyboard 925 and sysmouse drivers). Please ensure that either `options 926 RANDOMDEV' is present in your kernel config file or that 927 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 928 not have the /dev/random driver, OpenSSL (and consequently 929 lots of crypto tools (like SSH)) will fail with strange 930 errors. (see below, 20000624). 931 932 FreeBSD-current is safe again to run Crypto. 933 93420000709: 935 phk made the malloc default options AJ. This may slow things 936 down and uncover other latent bugs in the code. If you need to 937 run at full speed, you can disable this by doing the following: 938 ln -s aj /etc/malloc.conf 939 94020000706: 941 libftpio's version was accidentally bumped a few days ago. This 942 has been corrected. You may need to remove /usr/lib/libftpio.so.6 943 before doing your next buildworld/installworld pair. It certainly 944 won't hurt to remove it before the update procedure. It will 945 break fetch until a new one is built, but ftp can be used in the 946 interim if needed. 947 94820000705: 949 The crypto packages have changed for the cvsup. This has been done 950 in a backward compatible way, but the old packages will go away at 951 some point in the future. Look at /usr/share/examples/cvsup for 952 details. 953 95420000704: 955 With the new sys/modules/sound/drivers/*, you will need to 956 set SYSDIR until you do an installworld after July 7th. 957 95820000704: 959 rc.shutdown and rc will now call the rc.d scripts with start 960 or stop. This may cause some harmless warnings from older 961 rc.d scripts that haven't been updated. 962 96320000630: 964 The libfetch based version of fetch has gone into the tree. 965 Minor problems may result on some of the less popular sites, 966 which should be reported to des@freebsd.org. 967 96820000625: 969 From approximately this date forward, one must have the crypto 970 system installed in order to build the system and kernel. 971 While not technically strictly true, one should treat it as 972 required and grab the crypto bits. If you are grabbing CVS 973 trees, src-all and cvs-crypto should be treated as if they 974 were required. You should check with the latest collections 975 to make sure that these haven't changed. 976 97720000624: 978 Mark Murray just committed the first parts of a cleanup of 979 /dev/zero, et al. This is also cleaning up /dev/random. 980 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 981 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 982 until Mark can merge in the fixes to this work in progress. 983 openssh and openssl should not be used to generate keys from this 984 date to the completion of the work. 985 986 If you must operate at this reduced level of security, add ' 987 options RANDOMDEV' to your kernel or modload the randomdev 988 module. You may also need to copy a new MAKEDEV to /dev and 989 recreate the random and urandom devices. 990 99120000622: 992 The license on the softupdates is now a standard 2 clause 993 BSD license. You may need to remove your symbolic links 994 that used to be required when updating. 995 99620000621: 997 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 998 the config file update procedure. 999 http://people.freebsd.org/~imp/config-upd.html 1000 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1001 isn't buildable. However, you can generate a LINT file: 1002 cd /sys/<ARCH>/conf && make LINT 1003 100420000620: 1005 Binutils 2.10 have hit the tree, or will shortly. As soon 1006 as they do, the problem noted in 20000522 will be resolved and 1007 that workaround will no longer be required. 1008 100920000615: 1010 phk removed the compatibility creation of wd devices in the 1011 ad driver. If you haven't done so already, you must update 1012 your fstab, etc to use the ad devices instead of the wd 1013 devices. 1014 1015 In addition, you'll need to update your boot blocks to a 1016 more modern version, if you haven't already done so. Modern 1017 here means 4.0 release or newer (although older releases 1018 may work). 1019 102020000612: 1021 Peter took an axe to config(8). Be sure that you read his mail 1022 on the topic before even thinking about updating. You will 1023 need to create a /boot/device.hints or add a hints directive 1024 to your config file to compile them in statically. The format 1025 of the config file has changed as well. Please see GENERIC or 1026 NEWCARD for examples of the new format. 1027 1028 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1029 says that it has been fixed, assume that must use the hints mechanism 1030 in the loader if you need to use a machine with very old ISA cards 1031 in it. 1032 103320000522: 1034 A new set of binutils went into the tree today. Anybody 1035 building a kernel after this point is advised that they need 1036 to rebuild their binutils (or better yet do a 1037 buildworld/installworld) before building a new kernel. 1038 1039 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1040 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1041 is recommended that you don't set this option until the problem 1042 is resolved. 1043 104420000513: 1045 The ethernet drivers were all updated to clean up the BPF handling. 1046 104720000510: 1048 The problems with boot blocks on the alphas have been corrected. 1049 This will require some care in updating alphas. A new libstand 1050 is requires for the boot blocks to build properly. 1051 105220000503: 1053 Recompile all kld modules. Proper version dependency info 1054 is now available. 1055 105620000502: 1057 Modules have been disconnected from the buildworld tree and 1058 connected to the kernel building instead. 1059 106020000427: 1061 You may need to build gperf 1062 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1063 when upgrading from 4.0 -> current. The build system now uses 1064 an option only in -current. 1065 106620000417: 1067 The method that we brand ELF binaries has changed to be more 1068 acceptable to the binutils maintainers. You will need to 1069 rebrand your ELF binaries that aren't native. One problem 1070 binary is the Linux ldconfig. After your make world, but 1071 before you reboot, you'll need to issue: 1072 brandelf -t Linux /compat/linux/sbin/ldconfig 1073 if you have Linux compatibility enabled on your machine. 1074 107520000320: 1076 If you have really bad/marginal IDE drives, you may find they 1077 don't work well. Use pio mode instead. The easiest way to 1078 cope if you have a problem combination is to add: 1079 /sbin/sysctl hw.ata.ata_dma=0 1080 to the start of /etc/rc.conf. 1081 108220000319: 1083 The ISA and PCI compatibility shims have been connected to the 1084 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1085 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1086 include the appropriate option in your kernel config. Drivers 1087 using the shims should be updated or they won't ship with 1088 5.0-RELEASE, targeted for 2001. 1089 109020000318: 1091 We've entered the traditional post release dumping party. 1092 Large kernel changes are being committed and are in the 1093 works. It is important to keep the systems' klds and kernel 1094 in sync as kernel interfaces and structures are changing. 1095 Before reporting kernel panics, make sure that all modules 1096 that you are loading are up to date. 1097 109820000315: 1099 If you are upgrading from an older version of FreeBSD, you 1100 need to update your boot blocks as well. 'disklabel -B ad0' 1101 will do the trick. This isn't critical until you remove your 1102 wd device entries in /dev, at which point your system will not 1103 boot. 1104 110520000315: 1106 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1107 to upgrade to 4.0 from 3.x. 1108 1109COMMON ITEMS: 1110 1111 General Notes 1112 ------------- 1113 Avoid using make -j when upgrading. From time to time in the 1114 past there have been problems using -j with buildworld and/or 1115 installworld. This is especially true when upgrading between 1116 "distant" versions (eg one that cross a major release boundary 1117 or several minor releases, or when several months have passed 1118 on the -current branch). 1119 1120 Sometimes, obscure build problems are the result of environment 1121 poisoning. This can happen because the make utility reads its 1122 environment when searching for values for global variables. 1123 To run your build attempts in an "environmental clean room", 1124 prefix all make commands with 'env -i '. See the env(1) manual 1125 page for more details. 1126 1127 To build a kernel 1128 ----------------- 1129 If you are updating from a prior version of FreeBSD (even one just 1130 a few days old), you should follow this procedure. With a 1131 /usr/obj tree with a fresh buildworld, 1132 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1133 make installkernel KERNCONF=YOUR_KERNEL_HERE 1134 1135 To just build a kernel when you know that it won't mess you up 1136 -------------------------------------------------------------- 1137 cd src/sys/{i386,alpha}/conf 1138 config KERNEL_NAME_HERE 1139 cd ../../compile/KERNEL_NAME_HERE 1140 make depend 1141 make 1142 make install 1143 1144 If this fails, go to the "To build a kernel" section. 1145 1146 To rebuild everything and install it on the current system. 1147 ----------------------------------------------------------- 1148 # Note: sometimes if you are running current you gotta do more than 1149 # is listed here if you are upgrading from a really old current. 1150 1151 <make sure you have good level 0 dumps> 1152 <maybe fix /etc/fstab> [7] 1153 make buildworld 1154 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1155 make installkernel KERNCONF=YOUR_KERNEL_HERE 1156 [1] 1157 <reboot in single user> [3] 1158 mergemaster -p [5] 1159 make installworld 1160 mergemaster [4] 1161 <reboot> 1162 1163 1164 To cross-install current onto a separate partition 1165 -------------------------------------------------- 1166 # In this approach we use a separate partition to hold 1167 # current's root, 'usr', and 'var' directories. A partition 1168 # holding "/", "/usr" and "/var" should be about 2GB in 1169 # size. 1170 1171 <make sure you have good level 0 dumps> 1172 <boot into -stable> 1173 make buildworld 1174 <maybe newfs current's root partition> 1175 <mount current's root partition on directory ${CURRENT_ROOT}> 1176 make installworld DESTDIR=${CURRENT_ROOT} 1177 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1178 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \ 1179 ${CURRENT_ROOT}/boot/device.hints # as needed 1180 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1181 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1182 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1183 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1184 <reboot into current> 1185 <do a "native" rebuild/install as described in the previous section> 1186 <maybe install compatibility libraries from /usr/src/lib/compat> 1187 <reboot> 1188 1189 1190 To upgrade in-place from 4.x-stable to current 1191 ---------------------------------------------- 1192 # 5.x uses more space than 4.x. Also, the location of kernel 1193 # modules has changed. If you are installing 5.0 onto a 4.x 1194 # system, you'll need about 30MB of free disk space on your / 1195 # partition. If you have less than this, you may encounter difficult 1196 # to back out of problems with this procedure. If /tmp is on 1197 # the / partition, you may want to completely remove all its content 1198 # before upgrading, as this can be a common source of shortage of 1199 # space on /. 1200 1201 <make sure you have good level 0 dumps> 1202 <maybe fix /etc/fstab> [7] 1203 make buildworld [9] 1204 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1205 cp src/sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1206 make installkernel KERNCONF=YOUR_KERNEL_HERE 1207 cd src/sys/boot ; make install [6] 1208 [1] 1209 <reboot in single user> [3] 1210 mergemaster -p [5] 1211 rm -rf /usr/include/g++ 1212 make installworld 1213 mergemaster [4] 1214 <reboot> 1215 1216 Make sure that you've read the UPDATING file to understand the 1217 tweaks to various things you need. At this point in the life 1218 cycle of current, things change often and you are on your own 1219 to cope. The defaults can also change, so please read ALL of 1220 the UPDATING entries. 1221 1222 Also, if you are tracking -current, you must be subscribed to 1223 freebsd-current@freebsd.org. Make sure that before you update 1224 your sources that you have read and understood all the recent 1225 messages there. If in doubt, please track -stable which has 1226 much fewer pitfalls. 1227 1228 [1] If you have third party modules, such as vmware, you 1229 should disable them at this point so they don't crash your 1230 system on reboot. 1231 1232 [2] If you have legacy ISA devices, you may need to create 1233 your own device.hints to reflect your unique hardware 1234 configuration. 1235 1236 [3] From the bootblocks, boot -s, and then do 1237 fsck -p 1238 mount -u / 1239 mount -a 1240 cd /usr/src 1241 adjkerntz -i # if CMOS is wall time 1242 Also, when doing a major release upgrade, it is required that 1243 you boot into single user mode to do the installworld. 1244 For the 4.x -> 5.0 upgrade, you will also see many messages about 1245 needing to recompile your userland. These are harmless and can 1246 be ignored while you proceed to the next step. 1247 1248 [4] Note: This step is non-optional. Failure to do this step 1249 can result in a significant reduction in the functionality of the 1250 system. Attempting to do it by hand is not recommended and those 1251 that pursue this avenue should read this file carefully, as well 1252 as the archives of freebsd-current and freebsd-hackers mailing lists 1253 for potential gotchas. 1254 1255 [5] Usually this step is a noop. However, from time to time 1256 you may need to do this if you get unknown user in the following 1257 step. It never hurts to do it all the time. You may need to 1258 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1259 install) after the buildworld before this step if you last updated 1260 from current before 20020224 or from -stable before 20020408. 1261 1262 [6] 4.x boot loader can be used to boot a 5.x system, however 1263 it is difficult to do that at best. If you wish to try, then 1264 you should interrupt the boot and at the ok prompt type: 1265 ok unload 1266 ok boot /boot/kernel/kernel 1267 If this fails to work, you must install a new boot loader as 1268 described here. 1269 1270 [7] Before you upgrade, please make sure that you are not using 1271 compatibility slices. These are device names of the form, on i386 1272 and other architectures that use MBR slicing, /dev/ad0a without the 1273 actual slice name. Chances are excellent that these will break. 1274 You generally must update these entries to use the post FreeBSD 1275 2.x form of /dev/ad0s1a. 1276 1277 [8] In order to have a kernel that can run the 4.x binaries 1278 needed to do an installworld, you must include the COMPAT_FREEBSD4 1279 option in your kernel. Failure to do so may leave you with a system 1280 that is hard to boot to recover. 1281 1282 [9] When checking out sources, you must include the -P flag to have 1283 cvs prune empty directories. 1284FORMAT: 1285 1286This file contains a list, in reverse chronological order, of major 1287breakages in tracking -current. Not all things will be listed here, 1288and it only starts on March 15, 2000. Updating files can found in 1289previous releases if your system is older than this. 1290 1291Copyright information: 1292 1293Copyright 1998, 2002 M. Warner Losh.
