I upgraded from 2.1 to 3.0 two days ago. Everything went smooth except that
the install program overwrote my boot blocks with ffsv1 ones (all my
partitions are ffsv2).

Here is what I did:
- boot from install CD, start shell
# mount /dev/wd0a /mnt
# chroot /mnt
# cp /usr/mdec/boot /boot
# installboot -v -o timeout=5 /dev/rwd0a /usr/mdec/bootxx_ffsv2

[see 'man installboot']

I'm sending a PR right now.
