The purpose of relfs is to store objects on the underlying filesystem=20
(so that FAM is not necessary) and metadata on the db, but I am sure=20
that there will also be "external objects" e.g. all the objects that=20
have been seen by a web proxy connected to relfs, or all the objects=20
that have been backed up on a cdrom, which will have their metadata=20
held in the db. This means that we should store hashes for all files -=20
or some other "unique" identification method. Do hashing algorithms=20
operate on a per-block basis, so that modifications can be done=20
efficiently?
