This is correct on the clients.  On the ahcp server, you must configure
your interface manually, as you are used to do (e.g. with a "static"
block in /etc/network/interfaces).

This file is relevant only if you start ahcpd with /etc/init.d/ahcpd.
Ahcpd run from the command-line will ignore it.

Looks fine, provided your interfaces and routes are set accordingly in
/etc/network/interfaces.

As explained above, the interface must up and configured on the server
separately from ahcp.

If those are wireless nodes, do not forget to setup the wifi settings.
Also do not forget to bring the interface up (ifconfig ath0 up).

The "address familiy not supported" might be an IPv6 issue (do you have
IPv6 enabled?), but I am not sure.
