Thanks for the info.  I have no problems on the MacOS side.  I guess I was
more concerned about the NetBSD side, where it name your disks according
to, not the scsi id, but the number of scsi id's in the chain.

Currently, with a drive at scsi id 0, the MacOS disk is /dev/sd0x and my
NetBSD disk is /dev/sd1x.  Once the internal drive is gone, my NetBSD disk
will become /dev/sd0x since there are no other drives on the chain.

I guess that the procedure would be to move the drive, boot into single
user, edit the /etc/fstab file then boot to multi-user?  Am I missing
anything?
When I boot single user, do I have to remount the root filesystem as R/W
before I can edit the /etc/fstab?

Thanks,
Roger
