egrep 'NOSUID|NODEV' /sys/sys/mount.h
i.e., _IF_ the file system allowing user-mounts supports set-id
programs or devices, the mount code can disable them, if the FS is
being mounted by a user.
This is not a problem for either adosfs or for msdosfs, because
neither file system can contain either devices or set-id programs.
for the UFS or ISO-9660 file systems, however, it would be a problem.
When those file systems are fixed to allow user mounts, they'll have
that check put into them.
