If we do go down the road of having the DEINSTALL script check if the
daemon is running, then it should just abort the pkg_delete. After
all, at that point, it'll be obvious to the admin that he should kill
the daemon and pkg_delete again if he desires. Otherwise, it would be
bad to inadvertently kill a daemon and delete its package on a typo.

I can't think of any exceptions, but it does mean that we need to
extend all of those rc.d scripts to properly reply to a status
command. That pretty much calls for standalone rc.d scripts,
otherwise they won't work on pre-1.5 NetBSD systems.

Not really, but I question its need. I think the admin should really
be responsible and stop the daemon manually prior to pkg_deleting it.

I'll take care of PostgreSQL and Apache if we decide to head down this
