Some Mach/BSD distributions also had something like this ("nanny" was it?)
It struck me as a rather nice idea. No more "ps | grep sendmail ...
kill ... sendmail -bd -q1h" - just do "nanny restart sendmail".
One problem was that the super-daemon needs to know the pids of
the controlled daemons. They would usually put themselves
in the background, escaping nanny's tender care. All daemons
would need command line flags that tell them not to fork.
