Oh, did you! I'm reluctant to join that enormous thread, but there
have been couple things stated that aren't quite correct.

0) I agree that dnsmasq needs to be tested a lot more before it's
dnssec implementation can be as trusted as much as unbound's or

1) dnsmasq is used by ubuntu by default (at least), and it's at least
semi-integrated with network manager in that case over the dbus.

So far as I know the caching functionality in dnsmasq in that instance
is disabled due to fears about cache poisoning, that I don't fully
understand. My half understood fear translates into equivalent fears
for other local dns daemons.

2) Benchmarks like namebench can show the value of the local cache,
shaving milliseconds off of local queries across the network.

I have generally had servers have their own bind daemon for about 16
years - it helps, especially if you like to do reverse lookups.

3) I heartily approve of alternate dns servers like unbound or bind
being used by various distros of choice - a monoculture is not what is
needed here! Support and integration into NM for all of them would be

4) dnsmasq is now fully capable of obsoleting resolv.conf.auto cleverly
and dealing with at least some vagaries of vpns.

I was unaware of the dnssec-trigger stuff, which makes sense
especially on mobiles transiting captive-portal environments.

I would also like openwrt's captive portal stuff to work better.

I was also unaware of unbound's clever suspend resume support
for clearing the local cache.
