Possibly just the "reverse" of the startup deps?  For example, if baz is
dependent on foo and bar, the startup order is:

1. foo & bar (possibly parallel)
2. baz

at shutdown, we'd get the reverse:

1. baz
2. foo & bar (possibly parallel)

However, this may not be so easy for the total dependency graph of
everything under /etc/rc.d (not to forget /usr/local/etc/rc.d). ;)
