however, it fell appart here.  this is the error message i received:

WARNING: R/W mount of / denied.  Filesystem is not clean - run fsck
mount: /mnt/ad4s1a: Operation not permitted

the same error appears as before:

mknod: ad4s1a: Read-only file system
/sbin/mknod ad4s1

i have to say this was extremely helpful.  i was able to mount /dev/ad4s1e
under /usr.

however, i'm still stuck.  i was hoping i'd be able to create the device
nodes and then change the values under /etc/fstab so that things would
work without any issues.  but i'm still having a problem with sorting out
the device nodes.

any other advice on this one?

thanks again for this pretty sweet trick. :)
