The "OldFiles" mountpoint is itself duplicated in the backup volume, thus
creating a self-referential mount. The Transarc client disallows this, but
Arla sees nothing wrong. I suspect Arla should detect that a mountpoint
references the volume containing the mopuntpoint and disallow it, just as
the Transarc client does.
