Public bug reported: My dnsmasq instance uses "interface=br-vz0" and the interface br-vz0 is managed manually in /etc/network/interfaces.
During boot, dnsmasq is started before br-vz0 is created and this causes dnsmasq to exit: Jan 5 08:56:16 simon-laptop dnsmasq[1008]: dnsmasq: unknown interface br-vz0 Jan 5 08:56:16 simon-laptop dnsmasq[1008]: unknown interface br-vz0 Jan 5 08:56:16 simon-laptop dnsmasq[1008]: FAILED to start up Jan 5 08:56:17 simon-laptop NetworkManager[937]: <info> NetworkManager (version 1.0.4) is starting... ...
