> o can i just do the normal upgrade as described in UPDATING

Recently I updated a new Dell desktop from 4.9 to 5.x by
following /usr/src/UPDATING exactly. In particular I did:
mv /usr/src usr/src-4.9
mv /usr/obj/usr/src /usr/obj/usr/src-4.9
cvsup
make buildworld buildkernel installkernel
cp -p /sys/i386/conf/GENERIC.hints /boot/device.hints
cd /sys/boot; make install
reboot
<hit a key to interrupt the countdown after the kernel is loaded>
boot -s
mount -u /
mount -a
adjkerntz -i
mergemaster -p
rm -rf /usr/include/g++
make installworld
mergemaster
reboot
You can boot your old kernel if the first reboot fails. You
are pretty much commited to running -current after the
installworld so there is not much point in saving /usr/src as
I did. But make sure you are aware of -current changes and
where to find things in case something goes wrong. Having
another freebsd machine nearby would be handy.
ACPI gave me trouble so I just disabled it. This is one
thing worth knowing. From the boot loader, and before you do
boot -s, you can do
set hint.acpi.0.disabled=1
If that solves your problem, don't forget to add
hint.acpi.0.disabled="1"
in /boot/device.hints. There are finer grained knobs you
can play with.
> o is 5.2RC a good compromise choice?
Probably. If you happen to cvsup -current in the middle of
some major commit or breakage you can be in serious trouble.
At least for upgrade purposes -current seem to be reasonably
stable these days. Even so, after cvsupping I watched the
-current and cvs lists for a while for signs of problems
before attempting the above. Just unpack 5.2rc sources in
/usr/src and follow the same sequence.
