Updating Information for FreeBSD current users
This file is maintained by imp@village.org. Please send new entries
directly to him. See end of file for further details. For commonly
done items, please see the end of the file. Search for 'COMMON
ITEMS:'
20000612:
Peter took an axe to config(8). Besure that you read his mail
on the topic before even thinking about updating. More details
to follow.
20000522:
A new set of binutils went into the tree today. Anybody
building a kernel after this point is advised that they need
to rebuild their binutils (or better yet do a
buildworld/installworld) before building a new kernel.
Due to bugs in binutils, using malloc options (eg /etc/malloc.conf
or MALLOC_OPTIONS env var) J will cause ld to dump core. It
is recommended that you don't set this option until the problem
is resolved.
20000513:
The ethernet drivers were all updated to clean up the BPF handling.
20000510:
The problems with boot blocks on the alphas have been corrected.
This will require some care in updating alphas. A new libstand
is requires for the boot blocks to build properly.
20000503:
Recompile all kld modules. Proper version dependency info
is now available.
20000502:
Modules have been disconnected from the buildworld tree and
connected to the kernel building instead.
2000427:
You may need to build gperf
cd /usr/src/gnu/usr.bin/gperf && make depend all install
when upgrading from 4.0 -> current. The build system now uses
an option only in -current.
20000417:
The method that we brand ELF binaries has changed to be more
acceptible to the binutils maintainers. You will need to
rebrand your ELF binaries that aren't native. One problem
binary is the Linux ldconfig. After your make world, but
before you reboot, you'll neeed to issue:
brandelf -t Linux /compat/linux/sbin/ldconfig
if you have Linux compatibility enabled on your machine.
20000320:
If you have really bad/marginal IDE drives, you may find they
don't work well. Use pio mode instead. The easiest way to
cope if you have a problem combination is to add:
/sbin/sysctl -w hw.atamodes=pio,pio,pio,pio
to the start of /etc/rc.conf.
20000319:
The ISA and PCI compatability shims have been connected to the
options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old
style PCI or ISA drivers (i.e. tx, voxware, etc.) you must
include the appropriate option in your kernel config. Drivers
using the shims should be updated or they won't ship with
5.0-RELEASE, targeted for 2001.
20000318:
We've entered the tradtional post release dumping party.
Large kernel changes are being committed and are in the
works. It is important to keep the systems' klds and kernel
in sync as kernel interfaces and structures are changing.
Before reporting kernel panics, make sure that all modules
that you are loading are up to date.
20000315:
If you are upgrading from an older version of FreeBSD, you
need to update your boot blocks as well. 'disklabel -B ad0'
will do the trick. This isn't critical until you remove your
wd device entries in /dev, at which point your system will not
boot.
20000315:
4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how
to upgrade to 4.0 from 3.x.
COMMON ITEMS:
To build a kernel
-----------------
Update config, genassym and go:
config YOUR_KERNEL_HERE [1]
cd ../../compile/YOUR_KERNEL_HERE
make depend && make
make install
[1] If upgrading, add -r won't hurt and sometimes helps.
To rebuild everything
---------------------
make world
To upgrade from 4.0-stable to current
-------------------------------------
make buildworld
make buildkernel KERNEL=YOUR_KERNEL_HERE
make installkernel KERNEL=YOUR_KERNEL_HERE
make installworld
<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 cycloe of current, things change often and you are on
your own to cope.
FORMAT:
This file contains a list, in reverse chronologocal order, of major
breakages in tracking -current. Not all things will be listed here,
and it only starts on March 15, 2000. Updating files can found in
previous releases if your system is older than this.
Please filter your entries through Warner Losh (imp@village.org) so
that the style, formatting, etc of this file can be maintained.
