LXD on Manual incorrect resolv.conf

Tue Jun 26 23:45:22 UTC 2018

So…. Rick said there was a LP bug about bionic containers I looked at which
vaguely looked similar. But alas, they are all Xenial.

Basically as a starter for 10, I launched a Xenial host, added it to my
controller, deployed Mattermost and Postgres to containers on it, both
Xenial, and neither could talk to the internet so neither installed.
Adjusted the resolv.conf and they then installed, but then the resolv gets
zapped so they stop talking.
