** Description changed:
+ ============ 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.
