well, it's just a directory of files; but the names of the files are
encoded AFS inode numbers. The contents are exactly what you see
through the filesystem, but the names don't make it obvious what
you're looking at.

given that the fileserver is a userspace process, there shouldn't
really be much obstacle to getting it working.

even if you can't get a client working, you can take volume dumps from
a running server, and use for instance "dumptool" to get a tree of
files from it, named as you'd expect.
