For grins, I ran this on my build server. The resulting graph is... complex. But one thing was immediately clear: neither /etc/rc.d/dhclient and /etc/rc.d/natd depend on anything. That seems wrong: I would expect them to have some sort of dependency on NETWORKING, either BEFORE (since dhclient may be involved in bringing up the network) or REQUIRE (since it doesn’t make sense to run a networking daemon like natd before networking is up).
Or am I missing something?
