Comment 9 for bug 1701023

@smu-u can you please test with the vlan pkg from this ppa:
https://launchpad.net/~ddstreet/+archive/ubuntu/lp1701023

it fixes this specific issue in my test, but I'd like to make sure it works for you also.

I want to do some more testing with the change as well because ifupdown is so fragile in this area. This may also affect newer releases too, so I need to test those as well.
