Just to get this into the archives: ssh-host-config can certainly emit a
warning on non-system mounts, but having separate set of user mounts for
the SYSTEM user will also work just fine...  In fact, that'd make it
possible to have a whole different /etc/passwd (and /etc/group) file
readable only to SYSTEM (via a user mount).  Ugly, but workable... :-(
I'm by no means advocating the above setup, but I could think of some
situations where it might be useful (and it has come up a few times on
this list).
