Hypothetically, you could mount another file system over root using union-fs
and see that the arch meta-data lived in the mounted version instead of the
original (e.g. the arch meta-files would exist in a ghost directory
somewhere, pehaps, less visible to the system.

you would mount root as usual
in a subdirectroy, you would remount root (readonly)
then mount another arch-metadata directory over top (writeable)
so that any changes to the metadata would be written to the seocnd directory
-- then for updates/syncs, etc you would sync/update the union file system

I'd consider reading up on unionfs to see if this will work for you.


Also, I think the latest version of reiser supports version control build
in.
