I don't know which version of Sys V you are using.  Some cannot
support really long mount-point names.  That aside, you must be
sure that the shutdown shell command repeats its unmount-all
shell command pipe line for as many iterations as you have depth
of mounting.  The original has 2, which is fine for /usr/spool,
/usr/src, and /usr/tmp; but breaks down on (e.g.) /usr/src/add-ons.
