This would be good and work with dynamic SCSI devices as you point
out.
Story: Once I was mounting two new SCSI disks in a AIX box. The other
disks were in the volume manager. I had some problems with the
SCSI-ID switches in the cabinet and by mistake renumbered the already
used drives. The macine was then powered to see if it would discover
the newly mounted drives or not _this_ time. It came up and the
filesystems were all OK even though the underlying SCSI devices were
completely renumbered. I only discovered the renumbering mistake once
I re-examined the ID switches because the new drives did _not_ come
up. I was quite impressed when I realized what had happened and how
well AIX had handled it.
DEC-UNIX would not handle such a case. Linux _must_ because of the
dynamic numbering scheme we use.
