If your floppy drive is the NeXT floppy drive and not a 3rd party  
external, it's not a scsi device.

The way this works is by SCSI ID, not by physical arrangement on the  
bus.  So if your internal drives are SCSI 1 and SCSI 6, and your
CD is SCSI 4, your CD would be the second scsi device that the  
machine sees when it scans the bus.  (it starts at 0 and goes up,  
which isn't at all clear from this example).

This may be a security hole.  I'd be wary of running anything which  
allows access to the "mount" and "disk" commands as a setuid root  
program for everyone on the system, although I haven't investigated  
this thoroughly.
