I have the same problem on FreeBSD, it has been on my TODO for too long and
other unrelated priorities have eclipsed it from view. The trick would seem
to be modifying the kernel (or more likely init(8)) to keep track of which
daemon processes must announce their being ready or willing to die, or
something along similar lines. DGD would then be modified to register itself
as a longrunning daemon process requiring such special treatment.
