I had a misfortune to train thourougly booting from other devices than
a default sd0 :-).
The following procedure works consistently for me (assuming here that
sd2a, say, contains all files necessary for booting in a multi-user
mode).  Some steps are obviously for situations when you cannot boot
from sd0a and changing ID's is not an option for some reasons.
  a)  Boot from floppy (you have boot floppy, don't you?) in a single
      user mode and modify /etc/fstab on your intended boot device
      to mount the proper file system and not sd0a.  In our sample
      resulting line will be:
        /dev/sd2a /      4.3 rw,noquota,noauto 0 1
      instead of an original
        /dev/sd0a /      4.3 rw,noquota,noauto 0 1
      To get an access to this file you will have to mount
      ( say '/usr/etc/mount /dev/sd0a /tmp/hd') manually.
      Use -n option and writable directory if you are booting
      from CD-ROM or from floopy which starts CD-ROM.
      BTW - can somebody tell me how to use 'remount' option.
      Is not documented on 'man-page' and always barfs on me.
  b)  Go back to monitor and 'halt'.
  c)  At 'NeXT>' prompt type 'bsd(2,0,0)-a'.  This means 'ask
      for root device'.  An option 'rootdev=sd2' never worked for me.
  d)  When asked for root device type 'sd2' and hopefuly you are
      back in business.
  e)  Restore /etc/fstab to a pristine state.  You will likely
      forget that later and in that case you may start the whole
      procedure once again from scratch. :-)

Lets hope that you will never have to use that knowledge.
