system reboots: what version of OS?

permissions: do you have a way I can "test this"?

Note that I run ~150 jails right now across 4 servers, with unionfs used
to shared applications across them all to save on disk space ... I haven't
had a unionfs related panic of the server in quite awhile now (but I run
-STABLE faithfully), and haven't experienced any 'permissions' problems
that I know of, or that anyone has ever pointed out to me ...
