I don't see what's so hard about creating an ext2/3 partition for your
afs cache.  You should have a dedicated cache partition anyways.
Worst case you could use the -memcache option to afsd and skip the
persistent disk cache.

Because it needs direct access to the inodes via iget(); this works
for ext2/3, it does not work for reiserfs (or xfs, I believe) because
they (well, reiser for sure) breaks the user-space inode abstraction.
