    With supermount, you can change the disk in the drive whenever you want 
(with the obvious exception that you shouldn't do it when the filesystem is 
actively in use). You don't need to "cd" out of the directory first, and you 
don't need to tell the kernel what you're doing --- supermount will detect 
the media change automatically. 
     Supermount will automatically detect whether the media you are mounting 
is read-write or readonly, and if you mount a write-protected disk, then the 
subfs will be mounted as a readonly filesystem. 
     Supermount detects when you have finished activity on the subfs, and 
will flush all buffers to the disk before completing the operation. So, if 
you copy a file onto a supermounted floppy disk, the data will all be written 
to disk before the "cp" command finishes. When the command does complete, it 
will be safe to remove the disk. 

It goes without saying that floppies should not be ejected until the light 
has gone out on the drive.

Regards, Paul.
