And not very feasable. dhcpcd can be scripted to an extent, but not as much as

Yes. Infact that's how it was desgined. However, it only works well on Linux
boxes as you can have multiple default routes seperated by metric (lowest
wins), something which no BSD as yet supports. I could try and make each
dhcpcd instance talk to each other so one could replace the routes if one
fails and on the same subnet or provided different routes, but I've not done
that as yet as I think route metrics are a better idea.

It defends it's address about every 10 seconds, during which time it tries to
obtain a DHCP address. Sadly, IPv4LL suffers the same issue as above - the LL
route needs to work across >1 interface, which does not work on any BSD I
Infact, that would be a good SoC project. Allow NetBSD to support metrics in

No I'm not :)
I'm in gainful full time employment, but have been a SoC mentor for Gentoo.
I have the time to be a mentor for projects I know well, but not to be a
student. I'm an ex Gentoo dev, but still maintain the init system as an
external project which I aim to put into pkgsrc-wip soon as it boots my BSD
Has dnsmasq been considered? It's very compact, feature rich but GPL.
