UPDATING revision 164304
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 7Items affecting the ports and packages system can be found in 8/usr/ports/UPDATING. Please read that file before running 9portupgrade. 10 11NOTE TO PEOPLE WHO THINK THAT FreeBSD 7.x IS SLOW: 12 FreeBSD 7.x has many debugging features turned on, in 13 both the kernel and userland. These features attempt to detect 14 incorrect use of system primitives, and encourage loud failure 15 through extra sanity checking and fail stop semantics. They 16 also substantially impact system performance. If you want to 17 do performance measurement, benchmarking, and optimization, 18 you'll want to turn them off. This includes various WITNESS- 19 related kernel options, INVARIANTS, malloc debugging flags 20 in userland, and various verbose features in the kernel. Many 21 developers choose to disable these features on build machines 22 to maximize performance. 23 2420061113: 25 Support for PCI Message Signalled Interrupts on i386 and amd64 26 has been added to the kernel and various drivers will soon be 27 updated to use MSI when it is available. If there are any problems, 28 MSI can be disabled completely by setting the 'hw.pci.enable_msi' 29 and 'hw.pci.enable_msix' tunables to 0 in the loader. 30 3120061110: 32 The MUTEX_PROFILING option has been renamed to LOCK_PROFILING. 33 The lockmgr object layout has been changed as a result of having 34 a lock_object embedded in it. As a consequence all file system 35 kernel modules must be re-compiled. The mutex profiling man page 36 has not yet been updated to reflect this change. 37 3820061026: 39 KSE in the kernel has now been made optional and turned on by 40 default. Use 'nooption KSE' in your kernel config to turn it 41 off. All kernel modules *must* be recompiled after this change. 42 There-after, modules from a KSE kernel should be compatible with 43 modules from a NOKSE kernel due to the temporary padding fields 44 added to 'struct proc'. 45 4620060929: 47 mrouted and its utilities have been removed from the base system. 48 4920060927: 50 Some ioctl(2) command codes have changed. Full backward ABI 51 compatibility is provided if the "options COMPAT_FREEBSD6" is 52 present in the kernel configuration file. Make sure to add 53 this option to your kernel config file, or recompile X.Org 54 and the rest of ports; otherwise they may refuse to work. 55 5620060924: 57 tcpslice has been removed from the base system. 58 5920060913: 60 The sizes of struct tcpcb (and struct xtcpcb) have changed due to 61 the rewrite of TCP syncookies. Tools like netstat, sockstat, and 62 systat needs to be rebuilt. 63 6420060903: 65 libpcap updated to v0.9.4 and tcpdump to v3.9.4 66 6720060816: 68 The IPFIREWALL_FORWARD_EXTENDED option is gone and the behaviour 69 for IPFIREWALL_FORWARD is now as it was before when it was first 70 committed and for years after. The behaviour is now ON. 71 7220060725: 73 enigma(1)/crypt(1) utility has been changed on 64 bit architectures. 74 Now it can decrypt files created from different architectures. 75 Unfortunately, it is no longer able to decrypt a cipher text 76 generated with an older version on 64 bit architectures. 77 If you have such a file, you need old utility to decrypt it. 78 7920060709: 80 The interface version of the i4b kernel part has changed. So 81 after updating the kernel sources and compiling a new kernel, 82 the i4b user space tools in "/usr/src/usr.sbin/i4b" must also 83 be rebuilt, and vice versa. 84 8520060627: 86 The XBOX kernel now defaults to the nfe(4) driver instead of 87 the nve(4) driver. Please update your configuration 88 accordingly. 89 9020060514: 91 The i386-only lnc(4) driver for the AMD Am7900 LANCE and Am79C9xx 92 PCnet family of NICs has been removed. The new le(4) driver serves 93 as an equivalent but cross-platform replacement with the pcn(4) 94 driver still providing performance-optimized support for the subset 95 of AMD Am79C971 PCnet-FAST and greater chips as before. 96 9720060511: 98 The machdep.* sysctls and the adjkerntz utility have been 99 modified a bit. The new adjkerntz utility uses the new 100 sysctl names and sysctlbyname() calls, so it may be impossible 101 to run an old /sbin/adjkerntz utility in single-user mode 102 with a new kernel. Replace the `adjkerntz -i' step before 103 `make installworld' with: 104 105 /usr/obj/usr/src/sbin/adjkerntz/adjkerntz -i 106 107 and proceed as usual with the rest of the installworld-stage 108 steps. Otherwise, you risk installing binaries with their 109 timestamp set several hours in the future, especially if 110 you are running with local time set to GMT+X hours. 111 11220060412: 113 The ip6fw utility has been removed. The behavior provided by 114 ip6fw has been in ipfw2 for a good while and the rc.d scripts 115 have been updated to deal with it. There are some rules that 116 might not migrate cleanly. Use rc.firewall6 as a template to 117 rewrite rules. 118 11920060428: 120 The puc(4) driver has been overhauled. The ebus(4) and sbus(4) 121 attachments have been removed. Make sure to configure scc(4) 122 on sparc64. Note also that by default puc(4) will use uart(4) 123 and not sio(4) for serial ports because interrupt handling has 124 been optimized for multi-port serial cards and only uart(4) 125 implements the interface to support it. 126 12720060330: 128 The scc(4) driver replaces puc(4) for Serial Communications 129 Controllers (SCCs) like the Siemens SAB82532 and the Zilog 130 Z8530. On sparc64, it is advised to add scc(4) to the kernel 131 configuration to make sure that the serial ports remain 132 functional. 133 13420060317: 135 Most world/kernel related NO_* build options changed names. 136 New knobs have common prefixes WITHOUT_*/WITH_* (modelled 137 after FreeBSD ports) and should be set in /etc/src.conf 138 (the src.conf(5) manpage is provided). Full backwards 139 compatibility is maintained for the time being though it's 140 highly recommended to start moving old options out of the 141 system-wide /etc/make.conf file into the new /etc/src.conf 142 while also properly renaming them. More conversions will 143 likely follow. Posting to current@: 144 145 http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html 146 14720060305: 148 The NETSMBCRYPTO kernel option has been retired because its 149 functionality is always included in NETSMB and smbfs.ko now. 150 15120060303: 152 The TDFX_LINUX kernel option was retired and replaced by the 153 tdfx_linux device. The latter can be loaded as the 3dfx_linux.ko 154 kernel module. Loading it alone should suffice to get 3dfx support 155 for Linux apps because it will pull in 3dfx.ko and linux.ko through 156 its dependencies. 157 15820060204: 159 The 'audit' group was added to support the new auditing functionality 160 in the base system. Be sure to follow the directions for updating, 161 including the requirement to run mergemaster -p. 162 16320060201: 164 The kernel ABI to file system modules was changed on i386. 165 Please make sure that your kernel and modules are in sync. 166 16720060118: 168 This actually occured some time ago, but installing the kernel 169 now also installs a bunch of symbol files for the kernel modules. 170 This increases the size of /boot/kernel to about 67Mbytes. You 171 will need twice this if you will eventually back this up to kernel.old 172 on your next install. 173 If you have a shortage of room in your root partition, you should add 174 -DINSTALL_NODEBUG to your make arguments or add INSTALL_NODEBUG="yes" 175 to your /etc/make.conf. 176 17720060113: 178 libc's malloc implementation has been replaced. This change has the 179 potential to uncover application bugs that previously went unnoticed. 180 See the malloc(3) manual page for more details. 181 18220060112: 183 The generic netgraph(4) cookie has been changed. If you upgrade 184 kernel passing this point, you also need to upgrade userland 185 and netgraph(4) utilities like ports/net/mpd or ports/net/mpd4. 186 18720060106: 188 si(4)'s device files now contain the unit number. 189 Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f]. 190 19120060106: 192 The kernel ABI was mostly destroyed due to a change in the size 193 of struct lock_object which is nested in other structures such 194 as mutexes which are nested in all sorts of other structures. 195 Make sure your kernel and modules are in sync. 196 19720051231: 198 The page coloring algorithm in the VM subsystem was converted 199 from tuning with kernel options to autotuning. Please remove 200 any PQ_* option except PQ_NOOPT from your kernel config. 201 20220051211: 203 The net80211-related tools in the tools/tools/ath directory 204 have been moved to tools/tools/net80211 and renamed with a 205 "wlan" prefix. Scripts that use them should be adjusted 206 accordingly. 207 20820051202: 209 Scripts in the local_startup directories (as defined in 210 /etc/defaults/rc.conf) that have the new rc.d semantics will 211 now be run as part of the base system rcorder. If there are 212 errors or problems with one of these local scripts, it could 213 cause boot problems. If you encounter such problems, boot in 214 single user mode, remove that script from the */rc.d directory. 215 Please report the problem to the port's maintainer, and the 216 freebsd-ports@freebsd.org mailing list. 217 21820051129: 219 The nodev mount option was deprecated in RELENG_6 (where it 220 was a no-op), and is now unsupported. If you have nodev or dev listed 221 in /etc/fstab, remove it, otherwise it will result in a mount error. 222 22320051129: 224 ABI between ipfw(4) and ipfw(8) has been changed. You need 225 to rebuild ipfw(8) when rebuilding kernel. 226 22720051108: 228 rp(4)'s device files now contain the unit number. 229 Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f]. 230 23120051029: 232 /etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp. 233 Its /etc/rc.conf.d configuration file has been `ppp' from 234 the beginning, and hence there is no need to touch it. 235 23620051014: 237 Now most modules get their build-time options from the kernel 238 configuration file. A few modules still have fixed options 239 due to their non-conformant implementation, but they will be 240 corrected eventually. You may need to review the options of 241 the modules in use, explicitly specify the non-default options 242 in the kernel configuration file, and rebuild the kernel and 243 modules afterwards. 244 24520051001: 246 kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8) 247 to turn polling(4) on your interfaces. 248 24920050927: 250 The old bridge(4) implementation was retired. The new 251 if_bridge(4) serves as a full functional replacement. 252 25320050722: 254 The ai_addrlen of a struct addrinfo was changed to a socklen_t 255 to conform to POSIX-2001. This change broke an ABI 256 compatibility on 64 bit architecture. You have to recompile 257 userland programs that use getaddrinfo(3) on 64 bit 258 architecture. 259 26020050711: 261 RELENG_6 branched here. 262 26320050629: 264 The pccard_ifconfig rc.conf variable has been removed and a new 265 variable, ifconfig_DEFAULT has been introduced. Unlike 266 pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that 267 do not have ifconfig_ifn entries rather than just those in 268 removable_interfaces. 269 27020050616: 271 Some previous versions of PAM have permitted the use of 272 non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring 273 to third party PAM modules in /usr/local/lib. A change has been 274 made to require the use of absolute paths in order to avoid 275 ambiguity and dependence on library path configuration, which may 276 affect existing configurations. 277 27820050610: 279 Major changes to network interface API. All drivers must be 280 recompiled. Drivers not in the base system will need to be 281 updated to the new APIs. 282 28320050609: 284 Changes were made to kinfo_proc in sys/user.h. Please recompile 285 userland, or commands like `fstat', `pkill', `ps', `top' and `w' 286 will not behave correctly. 287 288 The API and ABI for hwpmc(4) have changed with the addition 289 of sampling support. Please recompile lib/libpmc(3) and 290 usr.sbin/{pmcstat,pmccontrol}. 291 29220050606: 293 The OpenBSD dhclient was imported in place of the ISC dhclient 294 and the network interface configuration scripts were updated 295 accordingly. If you use DHCP to configure your interfaces, you 296 must now run devd. Also, DNS updating was lost so you will need 297 to find a workaround if you use this feature. 298 299 The '_dhcp' user was added to support the OpenBSD dhclient. Be 300 sure to run mergemaster -p (like you are supposed to do every time 301 anyway). 302 30320050605: 304 if_bridge was added to the tree. This has changed struct ifnet. 305 Please recompile userland and all network related modules. 306 30720050603: 308 The n_net of a struct netent was changed to an uint32_t, and 309 1st argument of getnetbyaddr() was changed to an uint32_t, to 310 conform to POSIX-2001. These changes broke an ABI 311 compatibility on 64 bit architecture. With these changes, 312 shlib major of libpcap was bumped. You have to recompile 313 userland programs that use getnetbyaddr(3), getnetbyname(3), 314 getnetent(3) and/or libpcap on 64 bit architecture. 315 31620050528: 317 Kernel parsing of extra options on '#!' first lines of shell 318 scripts has changed. Lines with multiple options likely will 319 fail after this date. For full details, please see 320 http://people.freebsd.org/~gad/Updating-20050528.txt 321 32220050503: 323 The packet filter (pf) code has been updated to OpenBSD 3.7 324 Please note the changed anchor syntax and the fact that 325 authpf(8) now needs a mounted fdescfs(5) to function. 326 32720050415: 328 The NO_MIXED_MODE kernel option has been removed from the i386 329 amd64 platforms as its use has been superceded by the new local 330 APIC timer code. Any kernel config files containing this option 331 should be updated. 332 33320050227: 334 The on-disk format of LC_CTYPE files was changed to be machine 335 independent. Please make sure NOT to use NO_CLEAN buildworld 336 when crossing this point. Crossing this point also requires 337 recompile or reinstall of all locale depended packages. 338 33920050225: 340 The ifi_epoch member of struct if_data has been changed to 341 contain the uptime at which the interface was created or the 342 statistics zeroed rather then the wall clock time because 343 wallclock time may go backwards. This should have no impact 344 unless an snmp implementation is using this value (I know of 345 none at this point.) 346 34720050224: 348 The acpi_perf and acpi_throttle drivers are now part of the 349 acpi(4) main module. They are no longer built separately. 350 35120050223: 352 The layout of struct image_params has changed. You have to 353 recompile all compatibility modules (linux, svr4, etc) for use 354 with the new kernel. 355 35620050223: 357 The p4tcc driver has been merged into cpufreq(4). This makes 358 "options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or 359 compile in "device cpufreq" to restore this functionality. 360 36120050220: 362 The responsibility of recomputing the file system summary of 363 a SoftUpdates-enabled dirty volume has been transferred to the 364 background fsck. A rebuild of fsck(8) utility is recommended 365 if you have updated the kernel. 366 367 To get the old behavior (recompute file system summary at mount 368 time), you can set vfs.ffs.compute_summary_at_mount=1 before 369 mounting the new volume. 370 37120050206: 372 The cpufreq import is complete. As part of this, the sysctls for 373 acpi(4) throttling have been removed. The power_profile script 374 has been updated, so you can use performance/economy_cpu_freq in 375 rc.conf(5) to set AC on/offline cpu frequencies. 376 37720050206: 378 NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko) 379 requires recompiling libnetgraph and userland netgraph utilities. 380 38120050114: 382 Support for abbreviated forms of a number of ipfw options is 383 now deprecated. Warnings are printed to stderr indicating the 384 correct full form when a match occurs. Some abbreviations may 385 be supported at a later date based on user feedback. To be 386 considered for support, abbreviations must be in use prior to 387 this commit and unlikely to be confused with current key words. 388 38920041221: 390 By a popular demand, a lot of NOFOO options were renamed 391 to NO_FOO (see bsd.compat.mk for a full list). The old 392 spellings are still supported, but will cause annoying 393 warnings on stderr. Make sure you upgrade properly (see 394 the COMMON ITEMS: section later in this file). 395 39620041219: 397 Auto-loading of ancillary wlan modules such as wlan_wep has 398 been temporarily disabled; you need to statically configure 399 the modules you need into your kernel or explicitly load them 400 prior to use. Specifically, if you intend to use WEP encryption 401 with an 802.11 device load/configure wlan_wep; if you want to 402 use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp, 403 and wlan_xauth as required. 404 40520041213: 406 The behaviour of ppp(8) has changed slightly. If lqr is enabled 407 (``enable lqr''), older versions would revert to LCP ECHO mode on 408 negotiation failure. Now, ``enable echo'' is required for this 409 behaviour. The ppp version number has been bumped to 3.4.2 to 410 reflect the change. 411 41220041201: 413 The wlan support has been updated to split the crypto support 414 into separate modules. For static WEP you must configure the 415 wlan_wep module in your system or build and install the module 416 in place where it can be loaded (the kernel will auto-load 417 the module when a wep key is configured). 418 41920041201: 420 The ath driver has been updated to split the tx rate control 421 algorithm into a separate module. You need to include either 422 ath_rate_onoe or ath_rate_amrr when configuring the kernel. 423 42420041116: 425 Support for systems with an 80386 CPU has been removed. Please 426 use FreeBSD 5.x or earlier on systems with an 80386. 427 42820041110: 429 We have had a hack which would mount the root filesystem 430 R/W if the device were named 'md*'. As part of the vnode 431 work I'm doing I have had to remove this hack. People 432 building systems which use preloaded MD root filesystems 433 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in 434 their /etc/rc scripts. 435 43620041104: 437 FreeBSD 5.3 shipped here. 438 43920041102: 440 The size of struct tcpcb has changed again due to the removal 441 of RFC1644 T/TCP. You have to recompile userland programs that 442 read kmem for tcp sockets directly (netstat, sockstat, etc.) 443 44420041022: 445 The size of struct tcpcb has changed. You have to recompile 446 userland programs that read kmem for tcp sockets directly 447 (netstat, sockstat, etc.) 448 44920041016: 450 RELENG_5 branched here. For older entries, please see updating 451 in the RELENG_5 branch. 452 453COMMON ITEMS: 454 455 General Notes 456 ------------- 457 Avoid using make -j when upgrading. From time to time in the 458 past there have been problems using -j with buildworld and/or 459 installworld. This is especially true when upgrading between 460 "distant" versions (eg one that cross a major release boundary 461 or several minor releases, or when several months have passed 462 on the -current branch). 463 464 Sometimes, obscure build problems are the result of environment 465 poisoning. This can happen because the make utility reads its 466 environment when searching for values for global variables. 467 To run your build attempts in an "environmental clean room", 468 prefix all make commands with 'env -i '. See the env(1) manual 469 page for more details. 470 471 When upgrading from one major version to another it is generally 472 best to upgrade to the latest code in the currently installed branch 473 first, then do an upgrade to the new branch. This is the best-tested 474 upgrade path, and has the highest probability of being successful. 475 Please try this approach before reporting problems with a major 476 version upgrade. 477 478 To build a kernel 479 ----------------- 480 If you are updating from a prior version of FreeBSD (even one just 481 a few days old), you should follow this procedure. It is the most 482 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 483 484 make kernel-toolchain 485 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 486 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 487 488 To test a kernel once 489 --------------------- 490 If you just want to boot a kernel once (because you are not sure 491 if it works, or if you want to boot a known bad kernel to provide 492 debugging information) run 493 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 494 nextboot -k testkernel 495 496 To just build a kernel when you know that it won't mess you up 497 -------------------------------------------------------------- 498 This assumes you are already running a 5.X system. Replace 499 ${arch} with the architecture of your machine (e.g. "i386", 500 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 501 502 cd src/sys/${arch}/conf 503 config KERNEL_NAME_HERE 504 cd ../compile/KERNEL_NAME_HERE 505 make depend 506 make 507 make install 508 509 If this fails, go to the "To build a kernel" section. 510 511 To rebuild everything and install it on the current system. 512 ----------------------------------------------------------- 513 # Note: sometimes if you are running current you gotta do more than 514 # is listed here if you are upgrading from a really old current. 515 516 <make sure you have good level 0 dumps> 517 make buildworld 518 make kernel KERNCONF=YOUR_KERNEL_HERE 519 [1] 520 <reboot in single user> [3] 521 mergemaster -p [5] 522 make installworld 523 make delete-old 524 mergemaster [4] 525 <reboot> 526 527 528 To cross-install current onto a separate partition 529 -------------------------------------------------- 530 # In this approach we use a separate partition to hold 531 # current's root, 'usr', and 'var' directories. A partition 532 # holding "/", "/usr" and "/var" should be about 2GB in 533 # size. 534 535 <make sure you have good level 0 dumps> 536 <boot into -stable> 537 make buildworld 538 make buildkernel KERNCONF=YOUR_KERNEL_HERE 539 <maybe newfs current's root partition> 540 <mount current's root partition on directory ${CURRENT_ROOT}> 541 make installworld DESTDIR=${CURRENT_ROOT} 542 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 543 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 544 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 545 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 546 <reboot into current> 547 <do a "native" rebuild/install as described in the previous section> 548 <maybe install compatibility libraries from src/lib/compat> 549 <reboot> 550 551 552 To upgrade in-place from 5.x-stable to current 553 ---------------------------------------------- 554 <make sure you have good level 0 dumps> 555 make buildworld [9] 556 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 557 [1] 558 <reboot in single user> [3] 559 mergemaster -p [5] 560 make installworld 561 make delete-old 562 mergemaster -i [4] 563 <reboot> 564 565 Make sure that you've read the UPDATING file to understand the 566 tweaks to various things you need. At this point in the life 567 cycle of current, things change often and you are on your own 568 to cope. The defaults can also change, so please read ALL of 569 the UPDATING entries. 570 571 Also, if you are tracking -current, you must be subscribed to 572 freebsd-current@freebsd.org. Make sure that before you update 573 your sources that you have read and understood all the recent 574 messages there. If in doubt, please track -stable which has 575 much fewer pitfalls. 576 577 [1] If you have third party modules, such as vmware, you 578 should disable them at this point so they don't crash your 579 system on reboot. 580 581 [3] From the bootblocks, boot -s, and then do 582 fsck -p 583 mount -u / 584 mount -a 585 cd src 586 adjkerntz -i # if CMOS is wall time 587 Also, when doing a major release upgrade, it is required that 588 you boot into single user mode to do the installworld. 589 590 [4] Note: This step is non-optional. Failure to do this step 591 can result in a significant reduction in the functionality of the 592 system. Attempting to do it by hand is not recommended and those 593 that pursue this avenue should read this file carefully, as well 594 as the archives of freebsd-current and freebsd-hackers mailing lists 595 for potential gotchas. 596 597 [5] Usually this step is a noop. However, from time to time 598 you may need to do this if you get unknown user in the following 599 step. It never hurts to do it all the time. You may need to 600 install a new mergemaster (cd src/usr.sbin/mergemaster && make 601 install) after the buildworld before this step if you last updated 602 from current before 20020224 or from -stable before 20020408. 603 604 [8] In order to have a kernel that can run the 4.x binaries 605 needed to do an installworld, you must include the COMPAT_FREEBSD4 606 option in your kernel. Failure to do so may leave you with a system 607 that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 608 is required to run the 5.x binaries on more recent kernels. 609 610 Make sure that you merge any new devices from GENERIC since the 611 last time you updated your kernel config file. 612 613 [9] When checking out sources, you must include the -P flag to have 614 cvs prune empty directories. 615 616 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 617 "?=" instead of the "=" assignment operator, so that buildworld can 618 override the CPUTYPE if it needs to. 619 620 MAKEOBJDIRPREFIX must be defined in an environment variable, and 621 not on the command line, or in /etc/make.conf. buildworld will 622 warn if it is improperly defined. 623FORMAT: 624 625This file contains a list, in reverse chronological order, of major 626breakages in tracking -current. Not all things will be listed here, 627and it only starts on October 16, 2004. Updating files can found in 628previous releases if your system is older than this. 629 630Copyright information: 631 632Copyright 1998-2005 M. Warner Losh.
