  Does the cleanup script need to be run every time udhcpc dies?
A process supervisor can run a finish script that knows the exit code of
udhcpc, or the signal that killed it, but if there are moments when you
_don't_ want to run the cleanup script if udhcpc receives a SIGKILL, then
it's more complicated. A supervisor can only know how the service died,
it cannot know the state the service was in when it got killed.
