Because I don't want ANYONE messing with the raw underlying layer. I don't
want the administrators having access lest they get in the habbit of
"fixing" things. Our system really needs to track file creation &
deletion, so I want to lock everything off.

Konrad recently mentioned changing nullfs to permit self-overmounting.
We'll probably do something like that with our system. Given this
structuring, the restore daemon can't get at the underlying layer. :-)

Take care,
