11 NOTE 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.
25 Symbol versioning is enabled by default. To disable it, use
26 option WITHOUT_SYMVER. It is not advisable to attempt to
27 disable symbol versioning once it is enabled; your installworld
28 will break because a symbol version-less libc will get installed
29 before the install tools. As a result, the old install tools,
30 which previously had symbol dependencies to FBSD_1.0, will fail
31 because the freshly installed libc will not have them.
33 The default threading library has been changed to libthr. If
34 you wish to have libpthread as your default, use option
35 DEFAULT_THREAD_LIB=libpthread for the buildworld.
38 The ABI breakage in sendmail(8)'s libmilter has been repaired
39 so it is no longer necessary to recompile mail filters (aka,
40 milters). If you recompiled mail filters after the 20070408
41 note, it is not necessary to recompile them again.
44 The new trunk(4) driver has been renamed to lagg(4) as it better
45 reflects its purpose. ifconfig will need to be recompiled.
48 sendmail(8) has been updated to version 8.14.1. Mail filters
49 (aka, milters) compiled against the libmilter included in the
50 base operating system should be recompiled.
53 Firmwares for ipw(4) and iwi(4) are now included in the base tree.
54 In order to use them one must agree to the respective LICENSE in
55 share/doc/legal and define legal.intel_<name>.license_ack=1 via
56 loader.conf(5) or kenv(1). Make sure to deinstall the now
57 deprecated modules from the respective firmware ports.
60 The name resolution/mapping functions addr2ascii(3) and ascii2addr(3)
61 were removed from FreeBSD's libc. These originally came from INRIA
62 IPv6. Nothing in FreeBSD ever used them. They may be regarded as
63 deprecated in previous releases.
64 The AF_LINK support for getnameinfo(3) was merged from NetBSD to
65 replace it as a more portable (and re-entrant) API.
68 To support interrupt filtering a modification to the newbus API
69 has occurred, ABI was broken and __FreeBSD_version was bumped
70 to 700031. Please make sure that your kernel and modules are in
72 http://docs.freebsd.org/cgi/mid.cgi?20070221233124.GA13941
75 The IPv6 multicast forwarding code may now be loaded into GENERIC
76 kernels by loading the ip_mroute.ko module. This is built into the
77 module unless WITHOUT_INET6 or WITHOUT_INET6_SUPPORT options are
78 set; see src.conf(5) for more information.
81 The output of netstat -r has changed. Without -n, we now only
82 print a "network name" without the prefix length if the network
83 address and mask exactly match a Class A/B/C network, and an entry
84 exists in the nsswitch "networks" map.
85 With -n, we print the full unabbreviated CIDR network prefix in
86 the form "a.b.c.d/p". 0.0.0.0/0 is always printed as "default".
87 This change is in preparation for changes such as equal-cost
88 multipath, and to more generally assist operational deployment
89 of FreeBSD as a modern IPv4 router.
92 PIM has been turned on by default in the IPv4 multicast
93 routing code. The kernel option 'PIM' has now been removed.
94 PIM is now built by default if option 'MROUTING' is specified.
95 It may now be loaded into GENERIC kernels by loading the
99 Support for IPIP tunnels (VIFF_TUNNEL) in IPv4 multicast routing
100 has been removed. Its functionality may be achieved by explicitly
101 configuring gif(4) interfaces and using the 'phyint' keyword in
103 XORP does not support source-routed IPv4 multicast tunnels nor the
104 integrated IPIP tunneling, therefore it is not affected by this
105 change. The __FreeBSD_version macro has been bumped to 700030.
108 Support for PCI Message Signalled Interrupts has been
109 re-enabled in the bge driver, only for those chips which are
110 believed to support it properly. If there are any problems,
111 MSI can be disabled completely by setting the
112 'hw.pci.enable_msi' and 'hw.pci.enable_msix' tunables to 0
116 Support for PCI Message Signalled Interrupts has been
117 disabled again in the bge driver. Many revisions of the
118 hardware fail to support it properly. Support can be
119 re-enabled by removing the #define of BGE_DISABLE_MSI in
120 "src/sys/dev/bge/if_bge.c".
123 Support for PCI Message Signalled Interrupts has been added
124 to the bge driver. If there are any problems, MSI can be
125 disabled completely by setting the 'hw.pci.enable_msi' and
126 'hw.pci.enable_msix' tunables to 0 in the loader.
129 The removal of several facets of the experimental Threading
130 system from the kernel means that the proc and thread structures
131 have changed quite a bit. I suggest all kernel modules that might
132 reference these structures be recompiled.. Especially the
136 Sound infrastructure has been updated with various fixes and
137 improvements. Most of the changes are pretty much transparent,
138 with exceptions of followings:
139 1) All sound driver specific sysctls (hw.snd.pcm%d.*) have been
140 moved to their own dev sysctl nodes, for example:
141 hw.snd.pcm0.vchans -> dev.pcm.0.vchans
142 2) /dev/dspr%d.%d has been deprecated. Each channel now has its
143 own chardev in the form of "dsp%d.<function>%d", where <function>
144 is p = playback, r = record and v = virtual, respectively. Users
145 are encouraged to use these devs instead of (old) "/dev/dsp%d.%d".
146 This does not affect those who are using "/dev/dsp".
149 The following binaries have been disconnected from the build:
150 mount_devfs, mount_ext2fs, mount_fdescfs, mount_procfs, mount_linprocfs,
151 and mount_std. The functionality of these programs has been
152 moved into the mount program. For example, to mount a devfs
153 filesystem, instead of using mount_devfs, use: "mount -t devfs".
154 This does not affect entries in /etc/fstab, since entries in
155 /etc/fstab are always processed with "mount -t fstype".
158 Support for PCI Message Signalled Interrupts on i386 and amd64
159 has been added to the kernel and various drivers will soon be
160 updated to use MSI when it is available. If there are any problems,
161 MSI can be disabled completely by setting the 'hw.pci.enable_msi'
162 and 'hw.pci.enable_msix' tunables to 0 in the loader.
165 The MUTEX_PROFILING option has been renamed to LOCK_PROFILING.
166 The lockmgr object layout has been changed as a result of having
167 a lock_object embedded in it. As a consequence all file system
168 kernel modules must be re-compiled. The mutex profiling man page
169 has not yet been updated to reflect this change.
172 KSE in the kernel has now been made optional and turned on by
173 default. Use 'nooption KSE' in your kernel config to turn it
174 off. All kernel modules *must* be recompiled after this change.
175 There-after, modules from a KSE kernel should be compatible with
176 modules from a NOKSE kernel due to the temporary padding fields
177 added to 'struct proc'.
180 mrouted and its utilities have been removed from the base system.
183 Some ioctl(2) command codes have changed. Full backward ABI
184 compatibility is provided if the "options COMPAT_FREEBSD6" is
185 present in the kernel configuration file. Make sure to add
186 this option to your kernel config file, or recompile X.Org
187 and the rest of ports; otherwise they may refuse to work.
190 tcpslice has been removed from the base system.
193 The sizes of struct tcpcb (and struct xtcpcb) have changed due to
194 the rewrite of TCP syncookies. Tools like netstat, sockstat, and
195 systat needs to be rebuilt.
198 libpcap updated to v0.9.4 and tcpdump to v3.9.4
201 The IPFIREWALL_FORWARD_EXTENDED option is gone and the behaviour
202 for IPFIREWALL_FORWARD is now as it was before when it was first
203 committed and for years after. The behaviour is now ON.
206 enigma(1)/crypt(1) utility has been changed on 64 bit architectures.
207 Now it can decrypt files created from different architectures.
208 Unfortunately, it is no longer able to decrypt a cipher text
209 generated with an older version on 64 bit architectures.
210 If you have such a file, you need old utility to decrypt it.
213 The interface version of the i4b kernel part has changed. So
214 after updating the kernel sources and compiling a new kernel,
215 the i4b user space tools in "/usr/src/usr.sbin/i4b" must also
216 be rebuilt, and vice versa.
219 The XBOX kernel now defaults to the nfe(4) driver instead of
220 the nve(4) driver. Please update your configuration
224 The i386-only lnc(4) driver for the AMD Am7900 LANCE and Am79C9xx
225 PCnet family of NICs has been removed. The new le(4) driver serves
226 as an equivalent but cross-platform replacement with the pcn(4)
227 driver still providing performance-optimized support for the subset
228 of AMD Am79C971 PCnet-FAST and greater chips as before.
231 The machdep.* sysctls and the adjkerntz utility have been
232 modified a bit. The new adjkerntz utility uses the new
233 sysctl names and sysctlbyname() calls, so it may be impossible
234 to run an old /sbin/adjkerntz utility in single-user mode
235 with a new kernel. Replace the `adjkerntz -i' step before
236 `make installworld' with:
238 /usr/obj/usr/src/sbin/adjkerntz/adjkerntz -i
240 and proceed as usual with the rest of the installworld-stage
241 steps. Otherwise, you risk installing binaries with their
242 timestamp set several hours in the future, especially if
243 you are running with local time set to GMT+X hours.
246 The ip6fw utility has been removed. The behavior provided by
247 ip6fw has been in ipfw2 for a good while and the rc.d scripts
248 have been updated to deal with it. There are some rules that
249 might not migrate cleanly. Use rc.firewall6 as a template to
253 The puc(4) driver has been overhauled. The ebus(4) and sbus(4)
254 attachments have been removed. Make sure to configure scc(4)
255 on sparc64. Note also that by default puc(4) will use uart(4)
256 and not sio(4) for serial ports because interrupt handling has
257 been optimized for multi-port serial cards and only uart(4)
258 implements the interface to support it.
261 The scc(4) driver replaces puc(4) for Serial Communications
262 Controllers (SCCs) like the Siemens SAB82532 and the Zilog
263 Z8530. On sparc64, it is advised to add scc(4) to the kernel
264 configuration to make sure that the serial ports remain
268 Most world/kernel related NO_* build options changed names.
269 New knobs have common prefixes WITHOUT_*/WITH_* (modelled
270 after FreeBSD ports) and should be set in /etc/src.conf
271 (the src.conf(5) manpage is provided). Full backwards
272 compatibility is maintained for the time being though it's
273 highly recommended to start moving old options out of the
274 system-wide /etc/make.conf file into the new /etc/src.conf
275 while also properly renaming them. More conversions will
276 likely follow. Posting to current@:
278 http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html
281 The NETSMBCRYPTO kernel option has been retired because its
282 functionality is always included in NETSMB and smbfs.ko now.
285 The TDFX_LINUX kernel option was retired and replaced by the
286 tdfx_linux device. The latter can be loaded as the 3dfx_linux.ko
287 kernel module. Loading it alone should suffice to get 3dfx support
288 for Linux apps because it will pull in 3dfx.ko and linux.ko through
292 The 'audit' group was added to support the new auditing functionality
293 in the base system. Be sure to follow the directions for updating,
294 including the requirement to run mergemaster -p.
297 The kernel ABI to file system modules was changed on i386.
298 Please make sure that your kernel and modules are in sync.
301 This actually occured some time ago, but installing the kernel
302 now also installs a bunch of symbol files for the kernel modules.
303 This increases the size of /boot/kernel to about 67Mbytes. You
304 will need twice this if you will eventually back this up to kernel.old
305 on your next install.
306 If you have a shortage of room in your root partition, you should add
307 -DINSTALL_NODEBUG to your make arguments or add INSTALL_NODEBUG="yes"
308 to your /etc/make.conf.
311 libc's malloc implementation has been replaced. This change has the
312 potential to uncover application bugs that previously went unnoticed.
313 See the malloc(3) manual page for more details.
316 The generic netgraph(4) cookie has been changed. If you upgrade
317 kernel passing this point, you also need to upgrade userland
318 and netgraph(4) utilities like ports/net/mpd or ports/net/mpd4.
321 si(4)'s device files now contain the unit number.
322 Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f].
325 The kernel ABI was mostly destroyed due to a change in the size
326 of struct lock_object which is nested in other structures such
327 as mutexes which are nested in all sorts of other structures.
328 Make sure your kernel and modules are in sync.
331 The page coloring algorithm in the VM subsystem was converted
332 from tuning with kernel options to autotuning. Please remove
333 any PQ_* option except PQ_NOOPT from your kernel config.
336 The net80211-related tools in the tools/tools/ath directory
337 have been moved to tools/tools/net80211 and renamed with a
338 "wlan" prefix. Scripts that use them should be adjusted
342 Scripts in the local_startup directories (as defined in
343 /etc/defaults/rc.conf) that have the new rc.d semantics will
344 now be run as part of the base system rcorder. If there are
345 errors or problems with one of these local scripts, it could
346 cause boot problems. If you encounter such problems, boot in
347 single user mode, remove that script from the */rc.d directory.
348 Please report the problem to the port's maintainer, and the
349 freebsd-ports@freebsd.org mailing list.
352 The nodev mount option was deprecated in RELENG_6 (where it
353 was a no-op), and is now unsupported. If you have nodev or dev listed
354 in /etc/fstab, remove it, otherwise it will result in a mount error.
357 ABI between ipfw(4) and ipfw(8) has been changed. You need
358 to rebuild ipfw(8) when rebuilding kernel.
361 rp(4)'s device files now contain the unit number.
362 Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f].
365 /etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp.
366 Its /etc/rc.conf.d configuration file has been `ppp' from
367 the beginning, and hence there is no need to touch it.
370 Now most modules get their build-time options from the kernel
371 configuration file. A few modules still have fixed options
372 due to their non-conformant implementation, but they will be
373 corrected eventually. You may need to review the options of
374 the modules in use, explicitly specify the non-default options
375 in the kernel configuration file, and rebuild the kernel and
379 kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8)
380 to turn polling(4) on your interfaces.
383 The old bridge(4) implementation was retired. The new
384 if_bridge(4) serves as a full functional replacement.
387 The ai_addrlen of a struct addrinfo was changed to a socklen_t
388 to conform to POSIX-2001. This change broke an ABI
389 compatibility on 64 bit architecture. You have to recompile
390 userland programs that use getaddrinfo(3) on 64 bit
394 RELENG_6 branched here.
397 The pccard_ifconfig rc.conf variable has been removed and a new
398 variable, ifconfig_DEFAULT has been introduced. Unlike
399 pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that
400 do not have ifconfig_ifn entries rather than just those in
401 removable_interfaces.
404 Some previous versions of PAM have permitted the use of
405 non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring
406 to third party PAM modules in /usr/local/lib. A change has been
407 made to require the use of absolute paths in order to avoid
408 ambiguity and dependence on library path configuration, which may
409 affect existing configurations.
412 Major changes to network interface API. All drivers must be
413 recompiled. Drivers not in the base system will need to be
414 updated to the new APIs.
417 Changes were made to kinfo_proc in sys/user.h. Please recompile
418 userland, or commands like `fstat', `pkill', `ps', `top' and `w'
419 will not behave correctly.
421 The API and ABI for hwpmc(4) have changed with the addition
422 of sampling support. Please recompile lib/libpmc(3) and
423 usr.sbin/{pmcstat,pmccontrol}.
426 The OpenBSD dhclient was imported in place of the ISC dhclient
427 and the network interface configuration scripts were updated
428 accordingly. If you use DHCP to configure your interfaces, you
429 must now run devd. Also, DNS updating was lost so you will need
430 to find a workaround if you use this feature.
432 The '_dhcp' user was added to support the OpenBSD dhclient. Be
433 sure to run mergemaster -p (like you are supposed to do every time
437 if_bridge was added to the tree. This has changed struct ifnet.
438 Please recompile userland and all network related modules.
441 The n_net of a struct netent was changed to an uint32_t, and
442 1st argument of getnetbyaddr() was changed to an uint32_t, to
443 conform to POSIX-2001. These changes broke an ABI
444 compatibility on 64 bit architecture. With these changes,
445 shlib major of libpcap was bumped. You have to recompile
446 userland programs that use getnetbyaddr(3), getnetbyname(3),
447 getnetent(3) and/or libpcap on 64 bit architecture.
450 Kernel parsing of extra options on '#!' first lines of shell
451 scripts has changed. Lines with multiple options likely will
452 fail after this date. For full details, please see
453 http://people.freebsd.org/~gad/Updating-20050528.txt
456 The packet filter (pf) code has been updated to OpenBSD 3.7
457 Please note the changed anchor syntax and the fact that
458 authpf(8) now needs a mounted fdescfs(5) to function.
461 The NO_MIXED_MODE kernel option has been removed from the i386
462 amd64 platforms as its use has been superceded by the new local
463 APIC timer code. Any kernel config files containing this option
467 The on-disk format of LC_CTYPE files was changed to be machine
468 independent. Please make sure NOT to use NO_CLEAN buildworld
469 when crossing this point. Crossing this point also requires
470 recompile or reinstall of all locale depended packages.
473 The ifi_epoch member of struct if_data has been changed to
474 contain the uptime at which the interface was created or the
475 statistics zeroed rather then the wall clock time because
476 wallclock time may go backwards. This should have no impact
477 unless an snmp implementation is using this value (I know of
481 The acpi_perf and acpi_throttle drivers are now part of the
482 acpi(4) main module. They are no longer built separately.
485 The layout of struct image_params has changed. You have to
486 recompile all compatibility modules (linux, svr4, etc) for use
490 The p4tcc driver has been merged into cpufreq(4). This makes
491 "options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or
492 compile in "device cpufreq" to restore this functionality.
495 The responsibility of recomputing the file system summary of
496 a SoftUpdates-enabled dirty volume has been transferred to the
497 background fsck. A rebuild of fsck(8) utility is recommended
498 if you have updated the kernel.
500 To get the old behavior (recompute file system summary at mount
501 time), you can set vfs.ffs.compute_summary_at_mount=1 before
502 mounting the new volume.
505 The cpufreq import is complete. As part of this, the sysctls for
506 acpi(4) throttling have been removed. The power_profile script
507 has been updated, so you can use performance/economy_cpu_freq in
508 rc.conf(5) to set AC on/offline cpu frequencies.
511 NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko)
512 requires recompiling libnetgraph and userland netgraph utilities.
515 Support for abbreviated forms of a number of ipfw options is
516 now deprecated. Warnings are printed to stderr indicating the
517 correct full form when a match occurs. Some abbreviations may
518 be supported at a later date based on user feedback. To be
519 considered for support, abbreviations must be in use prior to
520 this commit and unlikely to be confused with current key words.
523 By a popular demand, a lot of NOFOO options were renamed
524 to NO_FOO (see bsd.compat.mk for a full list). The old
525 spellings are still supported, but will cause annoying
526 warnings on stderr. Make sure you upgrade properly (see
527 the COMMON ITEMS: section later in this file).
530 Auto-loading of ancillary wlan modules such as wlan_wep has
531 been temporarily disabled; you need to statically configure
532 the modules you need into your kernel or explicitly load them
533 prior to use. Specifically, if you intend to use WEP encryption
534 with an 802.11 device load/configure wlan_wep; if you want to
535 use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp,
536 and wlan_xauth as required.
539 The behaviour of ppp(8) has changed slightly. If lqr is enabled
540 (``enable lqr''), older versions would revert to LCP ECHO mode on
541 negotiation failure. Now, ``enable echo'' is required for this
542 behaviour. The ppp version number has been bumped to 3.4.2 to
546 The wlan support has been updated to split the crypto support
547 into separate modules. For static WEP you must configure the
548 wlan_wep module in your system or build and install the module
549 in place where it can be loaded (the kernel will auto-load
550 the module when a wep key is configured).
553 The ath driver has been updated to split the tx rate control
554 algorithm into a separate module. You need to include either
555 ath_rate_onoe or ath_rate_amrr when configuring the kernel.
558 Support for systems with an 80386 CPU has been removed. Please
559 use FreeBSD 5.x or earlier on systems with an 80386.
562 We have had a hack which would mount the root filesystem
563 R/W if the device were named 'md*'. As part of the vnode
564 work I'm doing I have had to remove this hack. People
565 building systems which use preloaded MD root filesystems
566 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in
567 their /etc/rc scripts.
570 FreeBSD 5.3 shipped here.
573 The size of struct tcpcb has changed again due to the removal
574 of RFC1644 T/TCP. You have to recompile userland programs that
575 read kmem for tcp sockets directly (netstat, sockstat, etc.)
578 The size of struct tcpcb has changed. You have to recompile
579 userland programs that read kmem for tcp sockets directly
580 (netstat, sockstat, etc.)
583 RELENG_5 branched here. For older entries, please see updating
584 in the RELENG_5 branch.
590 Avoid using make -j when upgrading. From time to time in the
591 past there have been problems using -j with buildworld and/or
592 installworld. This is especially true when upgrading between
593 "distant" versions (eg one that cross a major release boundary
594 or several minor releases, or when several months have passed
595 on the -current branch).
597 Sometimes, obscure build problems are the result of environment
598 poisoning. This can happen because the make utility reads its
599 environment when searching for values for global variables.
600 To run your build attempts in an "environmental clean room",
601 prefix all make commands with 'env -i '. See the env(1) manual
602 page for more details.
604 When upgrading from one major version to another it is generally
605 best to upgrade to the latest code in the currently installed branch
606 first, then do an upgrade to the new branch. This is the best-tested
607 upgrade path, and has the highest probability of being successful.
608 Please try this approach before reporting problems with a major
613 If you are updating from a prior version of FreeBSD (even one just
614 a few days old), you should follow this procedure. It is the most
615 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
617 make kernel-toolchain
618 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
619 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
621 To test a kernel once
622 ---------------------
623 If you just want to boot a kernel once (because you are not sure
624 if it works, or if you want to boot a known bad kernel to provide
625 debugging information) run
626 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
627 nextboot -k testkernel
629 To just build a kernel when you know that it won't mess you up
630 --------------------------------------------------------------
631 This assumes you are already running a 5.X system. Replace
632 ${arch} with the architecture of your machine (e.g. "i386",
633 "alpha", "amd64", "ia64", "pc98", "sparc64", etc).
635 cd src/sys/${arch}/conf
636 config KERNEL_NAME_HERE
637 cd ../compile/KERNEL_NAME_HERE
642 If this fails, go to the "To build a kernel" section.
644 To rebuild everything and install it on the current system.
645 -----------------------------------------------------------
646 # Note: sometimes if you are running current you gotta do more than
647 # is listed here if you are upgrading from a really old current.
649 <make sure you have good level 0 dumps>
651 make kernel KERNCONF=YOUR_KERNEL_HERE
653 <reboot in single user> [3]
661 To cross-install current onto a separate partition
662 --------------------------------------------------
663 # In this approach we use a separate partition to hold
664 # current's root, 'usr', and 'var' directories. A partition
665 # holding "/", "/usr" and "/var" should be about 2GB in
668 <make sure you have good level 0 dumps>
671 make buildkernel KERNCONF=YOUR_KERNEL_HERE
672 <maybe newfs current's root partition>
673 <mount current's root partition on directory ${CURRENT_ROOT}>
674 make installworld DESTDIR=${CURRENT_ROOT}
675 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
676 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
677 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
678 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
679 <reboot into current>
680 <do a "native" rebuild/install as described in the previous section>
681 <maybe install compatibility libraries from src/lib/compat>
685 To upgrade in-place from 5.x-stable to current
686 ----------------------------------------------
687 <make sure you have good level 0 dumps>
689 make kernel KERNCONF=YOUR_KERNEL_HERE [8]
691 <reboot in single user> [3]
698 Make sure that you've read the UPDATING file to understand the
699 tweaks to various things you need. At this point in the life
700 cycle of current, things change often and you are on your own
701 to cope. The defaults can also change, so please read ALL of
702 the UPDATING entries.
704 Also, if you are tracking -current, you must be subscribed to
705 freebsd-current@freebsd.org. Make sure that before you update
706 your sources that you have read and understood all the recent
707 messages there. If in doubt, please track -stable which has
710 [1] If you have third party modules, such as vmware, you
711 should disable them at this point so they don't crash your
714 [3] From the bootblocks, boot -s, and then do
719 adjkerntz -i # if CMOS is wall time
720 Also, when doing a major release upgrade, it is required that
721 you boot into single user mode to do the installworld.
723 [4] Note: This step is non-optional. Failure to do this step
724 can result in a significant reduction in the functionality of the
725 system. Attempting to do it by hand is not recommended and those
726 that pursue this avenue should read this file carefully, as well
727 as the archives of freebsd-current and freebsd-hackers mailing lists
728 for potential gotchas.
730 [5] Usually this step is a noop. However, from time to time
731 you may need to do this if you get unknown user in the following
732 step. It never hurts to do it all the time. You may need to
733 install a new mergemaster (cd src/usr.sbin/mergemaster && make
734 install) after the buildworld before this step if you last updated
735 from current before 20020224 or from -stable before 20020408.
737 [8] In order to have a kernel that can run the 4.x binaries
738 needed to do an installworld, you must include the COMPAT_FREEBSD4
739 option in your kernel. Failure to do so may leave you with a system
740 that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5
741 is required to run the 5.x binaries on more recent kernels.
743 Make sure that you merge any new devices from GENERIC since the
744 last time you updated your kernel config file.
746 [9] When checking out sources, you must include the -P flag to have
747 cvs prune empty directories.
749 If CPUTYPE is defined in your /etc/make.conf, make sure to use the
750 "?=" instead of the "=" assignment operator, so that buildworld can
751 override the CPUTYPE if it needs to.
753 MAKEOBJDIRPREFIX must be defined in an environment variable, and
754 not on the command line, or in /etc/make.conf. buildworld will
755 warn if it is improperly defined.
758 This file contains a list, in reverse chronological order, of major
759 breakages in tracking -current. Not all things will be listed here,
760 and it only starts on October 16, 2004. Updating files can found in
761 previous releases if your system is older than this.
