Bug description:
============ SRU justification ===========
Impact: lxc (by way of lxc-net) fails to start when dnsmasq is installed
Development fix: install a dnsmasq.d file to prevent the system-wide dnsmasq
from binding to lxcbr0
Stable fix: same as Development fix
Test case:
sudo apt-get purge lxc
sudo apt-get -y install dnsmasq
sudo apt-get -y install lxc
Regression potential: There should be none, since we are simply telling the
system-wide dnsmasq (if any) not to bind to the lxcbr0 which our own dnsmasq
instance will bind to.
==========================================
If dnsmasq is installed and running as default, it will bind all
interfaces. As a result lxc can't run dnsmasq against lxcbr0 (and
same with libvirt and virbr0).
At the least this should be documented in lxc. Preferably we'd find a
way to have dnsmasq be less of a bully.
