[Dnsmasq-discuss] Setting dns domain name through dhcpv6

[Dave Taht]

I'd like to note that we are trying to get away from resolve.conf.auto in a
couple cases, notably when you have multiple upstreams and you want reverse
queries to go to the right place.

A search list doesn't cut it in that case.

BUT supplying a search list makes sense to clients.
