This doesn't help in the case where mpd may take seconds to negotiate
with $provider for a link; always the case on ADSL here anyway, moreso
for dialup. The rc.d script exits after launching mpd, so named will
still start 'right away' while mpd - or ppp - is still negotiating.
I 'solved' this chicken-and-egg by adding an ugly sleep 7 after starting
(mpd &) before exiting the script. Haven't bothered refining what works
once a month or two, but the sleep could be killed by pid from an mpd-up
script as soon as there's a working link. (mpd 4.1 if it matters)

It's not mpd's error, or message; named knows nothing about mpd, but
does like its specified listen and *-source addresses to exist. This
one looks more like a ill-worded 'no route to host' indication perhaps?
Or trying to listen on the address of the (yet to exist) ng interface?

I've found named requires a proper /etc/rc.d/named stop / start cycle
after all required interfaces are up and there's a default route, here,
and that sleep 7 obviates that for me .. but it's hardly elegant.
cheers, Ian
