In a student lab you could make the reserved percentage so big that it
is unlikely that root (logs) and AFS (cache) fill the partition (both
root and AFS can write over that limit).

Hi Jason, you could loopbackmount an ext2. Maybe even tmpfs if you run
a client version that supports tmpfs as a cache file system. Just
don't forget to make a bigger swap in that case.
