Ah, good to know. But mount would complain when
trying to mount the same device twice, wouldn't it?
So comparison of files would still be difficult.

When doing several incremental backups one would end up
with a directory structure like this:
<root>
<all current dirs of backup n>
backup_<n-1>
<dirs of backup n-1>
backup_<n-2>
....
I wouldn't like such a layout, because comparison
with very old files would lead to a long and ugly
path name, and restoring a state cannot be done
with one cp command.
To prevent that one would have to be able to detect
the special backup directories and always keep them
at top level, which would require magic or help
by the user.
Or have I misunderstood your suggestion?
Bye, Patrick
