"Infinite storage!" > (1001 evil ;-}) Tape-as-mountable-FS requires a block addressable tape. Most QIC tapes do not qualify; most non-QIC helical scan tapes do not qualify. If you have a TK50 or 9track or other DEC SCSI tape drive, this is a possiblity (although remote). But how useful would it be? > What about ZIPFS, or CPIOFS? ZOOFS? ARCFS? LBRFS? ZIPFS (a per file compression layer that uses gzip compression) already exists as a senior project of two of John Heidemann's students at UCLA. This, of course, assumes we fix our stacking vnode implementation to better resemeble the FICUS design documents from which it was derived. > Punch-tape-FS > is possible, but it wouldn't be politically correct -- too many trees > would get cut down. ;-} You can use mylar for punch tape.
