Right!

Well, there still is in my case :)

That said, resolv.conf does not include it... I suppose the two fight
for the right to "be" in resolvconf?

Here's the output: http://paste.ubuntu.com/23396426/

[Desktop-packages] [Bug 1637700] Re: Caching dnsmasq stops resolving after some time

2016-10-29 Thread Thomas Hood 
In yakkety there is no longer supposed to be a local forwarding
nameserver (instance of dnsmasq) listening at 127.0.1.1. Instead an
instande of resolved is started. Name resolution requests are fed to it
via the name service switch (configured with nsswitch.conf) rather than
via the libc resolver (configured with resolv.conf).

Announcement: https://lists.ubuntu.com/archives/ubuntu-
devel/2016-May/039350.html

Please post the output of the /usr/share/resolvconf/dump-debug-info
utility.
