  We have been using nested file systems for many years on this system and
so far haven't had a single problem because of it.
  The problem of unmounting in sequence during shutdown can be solved
by using df instead of mount. Df reports the file systems in reverse
order. So the line:
df | sed -n -e '/\/tmp /d' -e '/\/ /d' -e 's/^.*(\(.*\)).*/umount \1/p' | sh -
will correctly unmount all file systems in a single pass. Note: the
above line of code was given to me by Jack Allen of Bell South.
