hosts?

these daemons only act upon INTERFACES with that condition.

if no interfaces have the condition, the daemon does nothing, but that's
reductionist.

you are throwing around "hosts", "client" and confusing things a lot.

It works like this:

    for (all interfaces) {
    	try the discovery protocol
	if (we learn something) {
	    change the interface
	   tell resolvd
	}
    }

Leading to this for both daemons:

    For all interfaces with the AUTOCONF flag set, the daemon attempts
    learning using a discovery protocol.
    If information is found it places an address onto the interface and
    provides DNS information to resolvd(8)

I don't see any need for describing the operation backwards.
