What I'm very interested in here are the failure cases and how we manage
them.  Punting the problem by saying "it's not NM's job to make sure DNS
is set up correctly" isn't an option I'm interested in, since NM is
often the only thing that's arbitrating between various sources of DNS
information.  At a minimum we need to verify that /etc/resolv.conf is
"correct" and we expect it to work.  But even just logging that fact
isn't really helpful, since that requires somebody to (a) find the logs
and (b) determine resolv.conf isn't correct, and (c) fix the problem
somehow.  There's a lot of places in the Linux networking stack for
stuff like this to fall through the cracks, and I'd like to reduce the
number of cracks instead of making more...
