file dedup (rather than block dedup) could mostly be handled at the
catalog level with another level of indirection.  I.e. instead of a
catalog entry containing file metadata and where the file lives on
media, it would contain file metadata and a foreign key to a table
that maps hashes to where the file lives on the media.
