[Bug 1531184] [NEW] dnsmasq doesn't start on boot because its interface isn't up yet

 

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:
