This is gonna conflict a bit with docker, and other users of network
namespaces, like systemd-nspawn. When docker runs, it picks up the
current /etc/resolv.conf and puts it in the container, but the container
itself runs in a network namespace, so it gets its own loopback device.
This will mean 127.0.0.1:53 points to the container itself, not the
host, so dns resolving in the container will not work.
Not sure how to fix something like that though...
