NOTE TO PEOPLE WHO THINK THAT FreeBSD 7.x IS SLOW:
|
|
FreeBSD 7.x has many debugging features turned on, in
|
|
both the kernel and userland. These features attempt to detect
|
|
incorrect use of system primitives, and encourage loud failure
|
|
through extra sanity checking and fail stop semantics. They
|
|
also substantially impact system performance. If you want to
|
|
do performance measurement, benchmarking, and optimization,
|
|
you'll want to turn them off. This includes various WITNESS-
|
|
related kernel options, INVARIANTS, malloc debugging flags
|
|
in userland, and various verbose features in the kernel. Many
|
|
developers choose to disable these features on build machines
|
|
to maximize performance.
|
|
|
|
20060929:
|
|
mrouted and its utilities have been removed from the base system.
|
|
|
|
20060927:
|
|
Some ioctl(2) command codes have changed. Full backward ABI
|
|
compatibility is provided if the "options COMPAT_FREEBSD6" is
|
|
present in the kernel configuration file. Make sure to add
|
|
this option to your kernel config file, or recompile X.Org
|
|
and the rest of ports; otherwise they may refuse to work.
|
|
|
|
20060924:
|
|
tcpslice has been removed from the base system.
|
|
|
|
20060913:
|
|
The sizes of struct tcpcb (and struct xtcpcb) have changed due to
|
|
the rewrite of TCP syncookies. Tools like netstat, sockstat, and
|
|
systat needs to be rebuilt.
|
|
|
|
20060903:
|
|
libpcap updated to v0.9.4 and tcpdump to v3.9.4
|
|
|
|
20060816:
|
|
The IPFIREWALL_FORWARD_EXTENDED option is gone and the behaviour
|
|
for IPFIREWALL_FORWARD is now as it was before when it was first
|
|
committed and for years after. The behaviour is now ON.
|
|
|
|
20060725:
|
|
enigma(1)/crypt(1) utility has been changed on 64 bit architectures.
|
|
Now it can decrypt files created from different architectures.
|
|
Unfortunately, it is no longer able to decrypt a cipher text
|
|
generated with an older version on 64 bit architectures.
|
|
If you have such a file, you need old utility to decrypt it.
|
|
|
|
20060709:
|
|
The interface version of the i4b kernel part has changed. So
|
|
after updating the kernel sources and compiling a new kernel,
|
|
the i4b user space tools in "/usr/src/usr.sbin/i4b" must also
|
|
be rebuilt, and vice versa.
|
|
|
|
20060627:
|
|
The XBOX kernel now defaults to the nfe(4) driver instead of
|
|
the nve(4) driver. Please update your configuration
|
|
accordingly.
|
|
|
|
20060514:
|
|
The i386-only lnc(4) driver for the AMD Am7900 LANCE and Am79C9xx
|
|
PCnet family of NICs has been removed. The new le(4) driver serves
|
|
as an equivalent but cross-platform replacement with the pcn(4)
|
|
driver still providing performance-optimized support for the subset
|
|
of AMD Am79C971 PCnet-FAST and greater chips as before.
|
|
|
|
20060511:
|
|
The machdep.* sysctls and the adjkerntz utility have been
|
|
modified a bit. The new adjkerntz utility uses the new
|
|
sysctl names and sysctlbyname() calls, so it may be impossible
|
|
to run an old /sbin/adjkerntz utility in single-user mode
|
|
with a new kernel. Replace the `adjkerntz -i' step before
|
|
`make installworld' with:
|
|
|
|
/usr/obj/usr/src/sbin/adjkerntz/adjkerntz -i
|
|
|
|
and proceed as usual with the rest of the installworld-stage
|
|
steps. Otherwise, you risk installing binaries with their
|
|
timestamp set several hours in the future, especially if
|
|
you are running with local time set to GMT+X hours.
|
|
|
|
20060412:
|
|
The ip6fw utility has been removed. The behavior provided by
|
|
ip6fw has been in ipfw2 for a good while and the rc.d scripts
|
|
have been updated to deal with it. There are some rules that
|
|
might not migrate cleanly. Use rc.firewall6 as a template to
|
|
rewrite rules.
|
|
|
|
20060428:
|
|
The puc(4) driver has been overhauled. The ebus(4) and sbus(4)
|
|
attachments have been removed. Make sure to configure scc(4)
|
|
on sparc64. Note also that by default puc(4) will use uart(4)
|
|
and not sio(4) for serial ports because interrupt handling has
|
|
been optimized for multi-port serial cards and only uart(4)
|
|
implements the interface to support it.
|
|
|
|
20060330:
|
|
The scc(4) driver replaces puc(4) for Serial Communications
|
|
Controllers (SCCs) like the Siemens SAB82532 and the Zilog
|
|
Z8530. On sparc64, it is advised to add scc(4) to the kernel
|
|
configuration to make sure that the serial ports remain
|
|
functional.
|
|
|
|
20060317:
|
|
Most world/kernel related NO_* build options changed names.
|
|
New knobs have common prefixes WITHOUT_*/WITH_* (modelled
|
|
after FreeBSD ports) and should be set in /etc/src.conf
|
|
(the src.conf(5) manpage is provided). Full backwards
|
|
compatibility is maintained for the time being though it's
|
|
highly recommended to start moving old options out of the
|
|
system-wide /etc/make.conf file into the new /etc/src.conf
|
|
while also properly renaming them. More conversions will
|
|
likely follow. Posting to current@:
|
|
|
|
http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html
|
|
|
|
20060305:
|
|
The NETSMBCRYPTO kernel option has been retired because its
|
|
functionality is always included in NETSMB and smbfs.ko now.
|
|
|
|
20060303:
|
|
The TDFX_LINUX kernel option was retired and replaced by the
|
|
tdfx_linux device. The latter can be loaded as the 3dfx_linux.ko
|
|
kernel module. Loading it alone should suffice to get 3dfx support
|
|
for Linux apps because it will pull in 3dfx.ko and linux.ko through
|
|
its dependencies.
|
|
|
|
20060204:
|
|
The 'audit' group was added to support the new auditing functionality
|
|
in the base system. Be sure to follow the directions for updating,
|
|
including the requirement to run mergemaster -p.
|
|
|
|
20060201:
|
|
The kernel ABI to file system modules was changed on i386.
|
|
Please make sure that your kernel and modules are in sync.
|
|
|
|
20060118:
|
|
This actually occured some time ago, but installing the kernel
|
|
now also installs a bunch of symbol files for the kernel modules.
|
|
This increases the size of /boot/kernel to about 67Mbytes. You
|
|
will need twice this if you will eventually back this up to kernel.old
|
|
on your next install.
|
|
If you have a shortage of room in your root partition, you should add
|
|
-DINSTALL_NODEBUG to your make arguments or add INSTALL_NODEBUG="yes"
|
|
to your /etc/make.conf.
|
|
|
|
20060113:
|
|
libc's malloc implementation has been replaced. This change has the
|
|
potential to uncover application bugs that previously went unnoticed.
|
|
See the malloc(3) manual page for more details.
|
|
|
|
20060112:
|
|
The generic netgraph(4) cookie has been changed. If you upgrade
|
|
kernel passing this point, you also need to upgrade userland
|
|
and netgraph(4) utilities like ports/net/mpd or ports/net/mpd4.
|
|
|
|
20060106:
|
|
si(4)'s device files now contain the unit number.
|
|
Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f].
|
|
|
|
20060106:
|
|
The kernel ABI was mostly destroyed due to a change in the size
|
|
of struct lock_object which is nested in other structures such
|
|
as mutexes which are nested in all sorts of other structures.
|
|
Make sure your kernel and modules are in sync.
|
|
|
|
20051231:
|
|
The page coloring algorithm in the VM subsystem was converted
|
|
from tuning with kernel options to autotuning. Please remove
|
|
any PQ_* option except PQ_NOOPT from your kernel config.
|
|
|
|
20051211:
|
|
The net80211-related tools in the tools/tools/ath directory
|
|
have been moved to tools/tools/net80211 and renamed with a
|
|
"wlan" prefix. Scripts that use them should be adjusted
|
|
accordingly.
|
|
|
|
20051202:
|
|
Scripts in the local_startup directories (as defined in
|
|
/etc/defaults/rc.conf) that have the new rc.d semantics will
|
|
now be run as part of the base system rcorder. If there are
|
|
errors or problems with one of these local scripts, it could
|
|
cause boot problems. If you encounter such problems, boot in
|
|
single user mode, remove that script from the */rc.d directory.
|
|
Please report the problem to the port's maintainer, and the
|
|
freebsd-ports@freebsd.org mailing list.
|
|
|
|
20051129:
|
|
The nodev mount option was deprecated in RELENG_6 (where it
|
|
was a no-op), and is now unsupported. If you have nodev or dev listed
|
|
in /etc/fstab, remove it, otherwise it will result in a mount error.
|
|
|
|
20051129:
|
|
ABI between ipfw(4) and ipfw(8) has been changed. You need
|
|
to rebuild ipfw(8) when rebuilding kernel.
|
|
|
|
20051108:
|
|
rp(4)'s device files now contain the unit number.
|
|
Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f].
|
|
|
|
20051029:
|
|
/etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp.
|
|
Its /etc/rc.conf.d configuration file has been `ppp' from
|
|
the beginning, and hence there is no need to touch it.
|
|
|
|
20051014:
|
|
Now most modules get their build-time options from the kernel
|
|
configuration file. A few modules still have fixed options
|
|
due to their non-conformant implementation, but they will be
|
|
corrected eventually. You may need to review the options of
|
|
the modules in use, explicitly specify the non-default options
|
|
in the kernel configuration file, and rebuild the kernel and
|
|
modules afterwards.
|
|
|
|
20051001:
|
|
kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8)
|
|
to turn polling(4) on your interfaces.
|
|
|
|
20050927:
|
|
The old bridge(4) implementation was retired. The new
|
|
if_bridge(4) serves as a full functional replacement.
|
|
|
|
20050722:
|
|
The ai_addrlen of a struct addrinfo was changed to a socklen_t
|
|
to conform to POSIX-2001. This change broke an ABI
|
|
compatibility on 64 bit architecture. You have to recompile
|
|
userland programs that use getaddrinfo(3) on 64 bit
|
|
architecture.
|
|
|
|
20050711:
|
|
RELENG_6 branched here.
|
|
|
|
20050629:
|
|
The pccard_ifconfig rc.conf variable has been removed and a new
|
|
variable, ifconfig_DEFAULT has been introduced. Unlike
|
|
pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that
|
|
do not have ifconfig_ifn entries rather than just those in
|
|
removable_interfaces.
|
|
|
|
20050616:
|
|
Some previous versions of PAM have permitted the use of
|
|
non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring
|
|
to third party PAM modules in /usr/local/lib. A change has been
|
|
made to require the use of absolute paths in order to avoid
|
|
ambiguity and dependence on library path configuration, which may
|
|
affect existing configurations.
|
|
|
|
20050610:
|
|
Major changes to network interface API. All drivers must be
|
|
recompiled. Drivers not in the base system will need to be
|
|
updated to the new APIs.
|
|
|
|
20050609:
|
|
Changes were made to kinfo_proc in sys/user.h. Please recompile
|
|
userland, or commands like `fstat', `pkill', `ps', `top' and `w'
|
|
will not behave correctly.
|
|
|
|
The API and ABI for hwpmc(4) have changed with the addition
|
|
of sampling support. Please recompile lib/libpmc(3) and
|
|
usr.sbin/{pmcstat,pmccontrol}.
|
|
|
|
20050606:
|
|
The OpenBSD dhclient was imported in place of the ISC dhclient
|
|
and the network interface configuration scripts were updated
|
|
accordingly. If you use DHCP to configure your interfaces, you
|
|
must now run devd. Also, DNS updating was lost so you will need
|
|
to find a workaround if you use this feature.
|
|
|
|
The '_dhcp' user was added to support the OpenBSD dhclient. Be
|
|
sure to run mergemaster -p (like you are supposed to do every time
|
|
anyway).
|
|
|
|
20050605:
|
|
if_bridge was added to the tree. This has changed struct ifnet.
|
|
Please recompile userland and all network related modules.
|
|
|
|
20050603:
|
|
The n_net of a struct netent was changed to an uint32_t, and
|
|
1st argument of getnetbyaddr() was changed to an uint32_t, to
|
|
conform to POSIX-2001. These changes broke an ABI
|
|
compatibility on 64 bit architecture. With these changes,
|
|
shlib major of libpcap was bumped. You have to recompile
|
|
userland programs that use getnetbyaddr(3), getnetbyname(3),
|
|
getnetent(3) and/or libpcap on 64 bit architecture.
|
|
|
|
20050528:
|
|
Kernel parsing of extra options on '#!' first lines of shell
|
|
scripts has changed. Lines with multiple options likely will
|
|
fail after this date. For full details, please see
|
|
http://people.freebsd.org/~gad/Updating-20050528.txt
|
|
|
|
20050503:
|
|
The packet filter (pf) code has been updated to OpenBSD 3.7
|
|
Please note the changed anchor syntax and the fact that
|
|
authpf(8) now needs a mounted fdescfs(5) to function.
|
|
|
|
20050415:
|
|
The NO_MIXED_MODE kernel option has been removed from the i386
|
|
amd64 platforms as its use has been superceded by the new local
|
|
APIC timer code. Any kernel config files containing this option
|
|
should be updated.
|
|
|
|
20050227:
|
|
The on-disk format of LC_CTYPE files was changed to be machine
|
|
independent. Please make sure NOT to use NO_CLEAN buildworld
|
|
when crossing this point. Crossing this point also requires
|
|
recompile or reinstall of all locale depended packages.
|
|
|
|
20050225:
|
|
The ifi_epoch member of struct if_data has been changed to
|
|
contain the uptime at which the interface was created or the
|
|
statistics zeroed rather then the wall clock time because
|
|
wallclock time may go backwards. This should have no impact
|
|
unless an snmp implementation is using this value (I know of
|
|
none at this point.)
|
|
|
|
20050224:
|
|
The acpi_perf and acpi_throttle drivers are now part of the
|
|
acpi(4) main module. They are no longer built separately.
|
|
|
|
20050223:
|
|
The layout of struct image_params has changed. You have to
|
|
recompile all compatibility modules (linux, svr4, etc) for use
|
|
with the new kernel.
|
|
|
|
20050223:
|
|
The p4tcc driver has been merged into cpufreq(4). This makes
|
|
"options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or
|
|
compile in "device cpufreq" to restore this functionality.
|
|
|
|
20050220:
|
|
The responsibility of recomputing the file system summary of
|
|
a SoftUpdates-enabled dirty volume has been transferred to the
|
|
background fsck. A rebuild of fsck(8) utility is recommended
|
|
if you have updated the kernel.
|
|
|
|
To get the old behavior (recompute file system summary at mount
|
|
time), you can set vfs.ffs.compute_summary_at_mount=1 before
|
|
mounting the new volume.
|
|
|
|
20050206:
|
|
The cpufreq import is complete. As part of this, the sysctls for
|
|
acpi(4) throttling have been removed. The power_profile script
|
|
has been updated, so you can use performance/economy_cpu_freq in
|
|
rc.conf(5) to set AC on/offline cpu frequencies.
|
|
|
|
20050206:
|
|
NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko)
|
|
requires recompiling libnetgraph and userland netgraph utilities.
|
|
|
|
20050114:
|
|
Support for abbreviated forms of a number of ipfw options is
|
|
now deprecated. Warnings are printed to stderr indicating the
|
|
correct full form when a match occurs. Some abbreviations may
|
|
be supported at a later date based on user feedback. To be
|
|
considered for support, abbreviations must be in use prior to
|
|
this commit and unlikely to be confused with current key words.
|
|
|
|
20041221:
|
|
By a popular demand, a lot of NOFOO options were renamed
|
|
to NO_FOO (see bsd.compat.mk for a full list). The old
|
|
spellings are still supported, but will cause annoying
|
|
warnings on stderr. Make sure you upgrade properly (see
|
|
the COMMON ITEMS: section later in this file).
|
|
|
|
20041219:
|
|
Auto-loading of ancillary wlan modules such as wlan_wep has
|
|
been temporarily disabled; you need to statically configure
|
|
the modules you need into your kernel or explicitly load them
|
|
prior to use. Specifically, if you intend to use WEP encryption
|
|
with an 802.11 device load/configure wlan_wep; if you want to
|
|
use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp,
|
|
and wlan_xauth as required.
|
|
|
|
20041213:
|
|
The behaviour of ppp(8) has changed slightly. If lqr is enabled
|
|
(``enable lqr''), older versions would revert to LCP ECHO mode on
|
|
negotiation failure. Now, ``enable echo'' is required for this
|
|
behaviour. The ppp version number has been bumped to 3.4.2 to
|
|
reflect the change.
|
|
|
|
20041201:
|
|
The wlan support has been updated to split the crypto support
|
|
into separate modules. For static WEP you must configure the
|
|
wlan_wep module in your system or build and install the module
|
|
in place where it can be loaded (the kernel will auto-load
|
|
the module when a wep key is configured).
|
|
|
|
20041201:
|
|
The ath driver has been updated to split the tx rate control
|
|
algorithm into a separate module. You need to include either
|
|
ath_rate_onoe or ath_rate_amrr when configuring the kernel.
|
|
|
|
20041116:
|
|
Support for systems with an 80386 CPU has been removed. Please
|
|
use FreeBSD 5.x or earlier on systems with an 80386.
|
|
|
|
20041110:
|
|
We have had a hack which would mount the root filesystem
|
|
R/W if the device were named 'md*'. As part of the vnode
|
|
work I'm doing I have had to remove this hack. People
|
|
building systems which use preloaded MD root filesystems
|
|
may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in
|
|
their /etc/rc scripts.
|
|
|
|
20041104:
|
|
FreeBSD 5.3 shipped here.
|
|
|
|
20041102:
|
|
The size of struct tcpcb has changed again due to the removal
|
|
of RFC1644 T/TCP. You have to recompile userland programs that
|
|
read kmem for tcp sockets directly (netstat, sockstat, etc.)
|
|

General Notes
|
|
-------------
|
|
Avoid using make -j when upgrading. From time to time in the
|
|
past there have been problems using -j with buildworld and/or
|
|
installworld. This is especially true when upgrading between
|
|
"distant" versions (eg one that cross a major release boundary
|
|
or several minor releases, or when several months have passed
|
|
on the -current branch).
|
|
|
|
Sometimes, obscure build problems are the result of environment
|
|
poisoning. This can happen because the make utility reads its
|
|
environment when searching for values for global variables.
|
|
To run your build attempts in an "environmental clean room",
|
|
prefix all make commands with 'env -i '. See the env(1) manual
|
|
page for more details.
|
|

When upgrading from one major version to another it is generally
|
|
best to upgrade to the latest code in the currently installed branch
|
|
first, then do an upgrade to the new branch. This is the best-tested
|
|
upgrade path, and has the highest probability of being successful.
|
|
Please try this approach before reporting problems with a major
|
|
version upgrade.

|
To build a kernel
|
|
-----------------
|
|
If you are updating from a prior version of FreeBSD (even one just
|
|
a few days old), you should follow this procedure. It is the most
|
|
failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
|
|
|
|
make kernel-toolchain
|
|
make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
|
|
make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
|
|
|
|
To test a kernel once
|
|
---------------------
|
|
If you just want to boot a kernel once (because you are not sure
|
|
if it works, or if you want to boot a known bad kernel to provide
|
|
debugging information) run
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
|
|
nextboot -k testkernel
|
|
|
|
To just build a kernel when you know that it won't mess you up
|
|
--------------------------------------------------------------
|
|
This assumes you are already running a 5.X system. Replace
|
|
${arch} with the architecture of your machine (e.g. "i386",
|
|
"alpha", "amd64", "ia64", "pc98", "sparc64", etc).
|
|
|
|
cd src/sys/${arch}/conf
|
|
config KERNEL_NAME_HERE
|
|
cd ../compile/KERNEL_NAME_HERE
|
|
make depend
|
|
make
|
|
make install
|
|
|
|
If this fails, go to the "To build a kernel" section.
|
|
|
|
To rebuild everything and install it on the current system.
|
|
-----------------------------------------------------------
|
|
# Note: sometimes if you are running current you gotta do more than
|
|
# is listed here if you are upgrading from a really old current.
|
|
|
|
<make sure you have good level 0 dumps>
|
|
make buildworld
|
|
make kernel KERNCONF=YOUR_KERNEL_HERE
|
|
[1]
|
|
<reboot in single user> [3]
|
|
mergemaster -p [5]
|
|
make installworld
|
|
make delete-old
|
|
mergemaster [4]
|
|
<reboot>
|
|
|
|
|
|
To cross-install current onto a separate partition
|
|
--------------------------------------------------
|
|
# In this approach we use a separate partition to hold
|
|
# current's root, 'usr', and 'var' directories. A partition
|
|
# holding "/", "/usr" and "/var" should be about 2GB in
|
|
# size.
|
|
|
|
<make sure you have good level 0 dumps>
|
|
<boot into -stable>
|
|
make buildworld
|
|
make buildkernel KERNCONF=YOUR_KERNEL_HERE
|
|
<maybe newfs current's root partition>
|
|
<mount current's root partition on directory ${CURRENT_ROOT}>
|
|
make installworld DESTDIR=${CURRENT_ROOT}
|
|
make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
|
|
make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
|
|
cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
|
|
<edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
|
|
<reboot into current>
|
|
<do a "native" rebuild/install as described in the previous section>
|
|
<maybe install compatibility libraries from src/lib/compat>
|
|
<reboot>
|
|
|
|
|
|
To upgrade in-place from 5.x-stable to current
|
|
----------------------------------------------
|
|
<make sure you have good level 0 dumps>
|
|
make buildworld [9]
|
|
make kernel KERNCONF=YOUR_KERNEL_HERE [8]
|
|
[1]
|
|
<reboot in single user> [3]
|
|
mergemaster -p [5]
|
|
make installworld
|
|
make delete-old
|
|
mergemaster -i [4]
|
|
<reboot>
|
|
|
|
Make sure that you've read the UPDATING file to understand the
|
|
tweaks to various things you need. At this point in the life
|
|
cycle of current, things change often and you are on your own
|
|
to cope. The defaults can also change, so please read ALL of
|
|
the UPDATING entries.
|
|
|
|
Also, if you are tracking -current, you must be subscribed to
|
|
freebsd-current@freebsd.org. Make sure that before you update
|
|
your sources that you have read and understood all the recent
|
|
messages there. If in doubt, please track -stable which has
|
|
much fewer pitfalls.
|
|
|
|
[1] If you have third party modules, such as vmware, you
|
|
should disable them at this point so they don't crash your
|
|
system on reboot.
|
|
|
|
[3] From the bootblocks, boot -s, and then do
|
|
fsck -p
|
|
mount -u /
|
|
mount -a
|
|
cd src
|
|
adjkerntz -i # if CMOS is wall time
|
|
Also, when doing a major release upgrade, it is required that
|
|
you boot into single user mode to do the installworld.
|
|
|
|
[4] Note: This step is non-optional. Failure to do this step
|
|
can result in a significant reduction in the functionality of the
|
|
system. Attempting to do it by hand is not recommended and those
|
|
that pursue this avenue should read this file carefully, as well
|
|
as the archives of freebsd-current and freebsd-hackers mailing lists
|
|
for potential gotchas.
|
|
|
|
[5] Usually this step is a noop. However, from time to time
|
|
you may need to do this if you get unknown user in the following
|
|
step. It never hurts to do it all the time. You may need to
|
|
install a new mergemaster (cd src/usr.sbin/mergemaster && make
|
|
install) after the buildworld before this step if you last updated
|
|
from current before 20020224 or from -stable before 20020408.
|
|
|
|
[8] In order to have a kernel that can run the 4.x binaries
|
|
needed to do an installworld, you must include the COMPAT_FREEBSD4
|
|
option in your kernel. Failure to do so may leave you with a system
|
|
that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5
|
|
is required to run the 5.x binaries on more recent kernels.
|
|
|
|
Make sure that you merge any new devices from GENERIC since the
|
|
last time you updated your kernel config file.
|
|
|
|
[9] When checking out sources, you must include the -P flag to have
|
|
cvs prune empty directories.
|
|
|
|
If CPUTYPE is defined in your /etc/make.conf, make sure to use the
|
|
"?=" instead of the "=" assignment operator, so that buildworld can
|
|
override the CPUTYPE if it needs to.
|
|
|
|
MAKEOBJDIRPREFIX must be defined in an environment variable, and
|
|
not on the command line, or in /etc/make.conf. buildworld will
|
|
warn if it is improperly defined.
|
|
FORMAT:
|
|
|
|
This file contains a list, in reverse chronological order, of major
|
|
breakages in tracking -current. Not all things will be listed here,
|
|
and it only starts on October 16, 2004. Updating files can found in
|
|
previous releases if your system is older than this.
