As I said, that DOES NOT WORK.

change fstab so that wd0 is replaced with wd4 on all lines.

boot with -a

I am given a list of the drives as seen. Choose wd4.

Some error like when it is trying to mount (out of my head so not 100%
correct):

(No such file or dir) cannot stat wd4e /usr

I drop to a shell and I am unable to mount anything from wd4. df -h
show that / is still mounted at root_device and not /

Now the old fstab had:

/dev/wd0a / ffs rw,softdep 1 1
/dev/wd0f /home ffs rw,nodev,nosuid,softdep 1 2
/dev/wd0e /tmp ffs rw,nodev,nosuid,async 1 2
/dev/wd0d /usr ffs rw,nodev,softdep 1 2

I change this to replace wd4 for everything, reboot boot with the -a
and pick wd4

No Love.

BTW, I dropped a Gentoo Linux CD in the drive and booted it. It also
see the device order as OBSD, however it respects the original boot
order and does not reorder the drives. I would consider this to be the
correct behavior. What does everyone else think?
