Comment 68 for bug 1573272

Testing on trusty, same (except interface names, e.g. ens7 -> eth1, etc) e/n/i config as comment 61. I could not use the systemd change from comment 8, since trusty uses upstart, and I could not find the proper place in upstart code to introduce a delay to more easily reproduce the bug, but I did verify that the -proposed package results in the correct result:

$ dpkg -l | grep vlan
ii vlan 1.9-3ubuntu10.4
