You misundestand. devd *CANNOT* do this. I have a laptop that has a
builtin rl0 interface. I plug in a wi0 interface. somehow we gotta
deal.
and you cannot tell dhclient that interfaces have arrived.

why is this evil? dhclient can and does run on mulitple interfaces.
it fails now because it specifically precludes it, but for no other
good reasons.
