I think it would be a great idea to add a rc.conf variable that would
control the behaviour of dhclient and dns. In windows for example, when
you set to use DHCP for an interface, you are given the option to obtain
DNS from DHCP or set is statically. Simillar functionality via rc.conf
variables would be ideal in my opinion.
