Yes, I look forward to his patches, but there is still a fstab check
in umount. The current umount(8) code expects "user" or "users" option
in /etc/mtab (or in Miklos's /proc/mounts) and *also* in /etc/fstab.
Maybe the umount(8) code is too much paranoid and we needn't the
fstab check, especially with non-suid umount(2). Miklos's patches
also add support for "a submount under the owned mount" -- this is
probably next situation when check against fstab is useless.
