P.S. Will mounts in a non-global zone force nodev, or will
unauthorized device nodes be disabled by some other means?
Mounts are

Therefore, mounts within a non-global zone are
restricted to a
given allowed list of filesystems, as described
in Section 5 and
Section 6. This applies to all mounts not just
lofi ones.

The default list of allowed filesystems is based

Allowing lofi devices into non-global zones
introduces a security
issue. Some filesystems (notably UFS) are not
sufficiently protected
against corrupted or maliciously constructed
filesystem images,
which lofi allows the zone root user to modify.
This could
potentially lead to a
