I don't agree that it is nicer to do this in cramfs.  I prefer the
technique of union of a tmpfs over some other fs because a single
solution that works with all filesystems is better than re-implementing
the same idea in multiple filesystems.  Multiple implementations is a
recipe for bugs and feature mismatch.
