references to user written filesystems

[steve kneuper]

I've recently started to look into Unix file system abstractions - the system 
V file system switch, the vnode that Sun has and the gnode that Ultrix uses.  I
am curious if other people out there are looking at constructing their own file
system; what problem they are trying to solve.  I've seen a couple articles 
from DEC about supporting MSDOS and VMS file systems under Ultrix with the 
GNODE switch ....

We're hoping to build a user written filesystem to do storage management - move
unreferenced data sets off of the file system onto tape, recalling those data
sets when referenced by the filesystem. DF would, on such a filesystem, return
some sysgen defined size of the file system partition...
