WORM drives anyone ?

Simpson Garfinkle designed and implemented a WORM filesystem (WOFS) while
at the Media Lab at MIT. It integrates most easily into a BSD UNIX
environment through an NFS interface; he had a prototype user-mode
NFS server running on a Sun. It also looks promising for the System
5.3 file system switch. You might contact him for more details:
simsong at athena.mit.edu should suffice.
Needless to say, a properly layered SCSI driver with media-dependent
top-ends (hard disk, tape, WORM) and a controller-dependent SCSI
bottom end is also essential. If you hunt for off-the-shelf drivers,
you'll usually find that a SCSI driver will insist on treating a WORM like
a hard disk, a paradigm which is at best incomplete.
