OK, that sounds like a plan.  There's one problem, though -- I really need
to do this in a single step (i.e. I won't have console access to issue any
commands after all processes have been killed off and all the world's got
is a root shell), so the script mustn't get killed while the system is coming
down.

Thanks for help,
