[geeks] Versioning FIlesystem

[David de Gruyl]

This is a somewhat esoteric question, as I have no plans to change over 
to a versioning filesystem.  But when other users are involved it could 
be very useful to have a "undelete" function, and I have found version 
tracking to be quite useful, especially for configuration files.

On VMS systems, the filesystem keeps old copies of files around for 
recovery.  THis is a circular number, with a per file (i think) 
configuration, so that only a maximum of n copies of a file are ever 
around.

I am interested if anything like this exists for UNIX based OSes.  I 
know that SCO has a versioning option for their filesystem, but I am 
unaware of anything like this for the BSDs or even for linux, although 
it looks like something may exist.
