Public bug reported:
The following simple netplan config results in a 2-minut unneccessary
delay on boot. Everything works like it should in the end. The bridge
has no interfaces due to a regression in Ubuntu migrating to netplan
(see https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/1779341).
