Definitely dnsmasq.

I don't think it's really a different problem.
Resolvers that are turned on all the time could use 5011 if they wanted.
A "rfc5011d" could dpkg-divert the TAs and update them at the right time.

Yes, it does open up windows of vulnerability, and it seems like forcing
someone to open that window would be relatively easy. "Did you try turning it
off and on?"-type support often then becomes "factory reset it"...

Factory resetting a home router might also wipe out rfc5011 updates too.

So I'd really like to solve this problem, and if we do, then it makes the
distro-update-package way of getting TAs much less critical.
