Change your /etc/fstab root filesystem entry.
You obviously haven't been reading the cvs-all
mailing list and thus should not be running current.
from:
/dev/wd0a / ufs rw 1 1
to:
/dev/wd0s2a / ufs rw 1 1

"If it is true that our Universe has a zero net value for all conserved
quantities, then it may simply be a fluctuation of the vacuum of some
larger space in which our Universe is imbedded. In answer to the
question of why it happened, I offer the modest proposal that our
Universe is simply one of those things which happen from time to time."

*WARNING*
If your boot disk is sliced (has a partition table), and you have not
upgraded /sbin/mount to the most recent version preceeding this change,
you will have problems booting.
This change means that if your current /etc/fstab looks like this:
/dev/xd0a / ufs ...
/dev/xd0s2e /usr ufs ...
you need to update it to look like:
/dev/xd0s2a / ufs ...
/dev/xd0s2e /usr ufs ...
Note that the root filesystem is now consistent with the others. If
you are using a 'dedicated' disk, you will have entries like
/dev/xd0a / ufs ...
/dev/xd0e /usr ufs ...
and you should *not* change.
The recent update to /sbin/mount includes compatability support which
will ease this transition.
