ok thnx, I will set that up and try it to reproduce

indeed, i've thought about trying to fix that behavior in the past, but as you can see touching ifupdown and everything around it is rather dangerous, and the bonds work during bootup, so I never bothered. Hopefully with Bionic everyone will move to using systemd-networkd...?

> Just to summarize: it is a duplicate of the other bug and it is fixed by your patch!

Ok, well that is good - I'm still trying to reproduce because I want to make sure I'm covering everything correctly. I have to make sure the original bug 1573272 remains "fixed", but also fix this bug, and not introduce any other regressions.

Also I understand this has been breaking things for you, but because of the fragile nature of ifupdown (and the various if-pre-up.d scripts added onto it), I don't want to rush this fix, so I'd like to review things more deeply and do more testing next week, before starting an SRU for this. You are welcome to use my ppa package in the meantime, if that helps you, and the versioning on the PPA build is such that any official vlan package should replace my ppa build, when this is fixed in the future.

I'll re-mark this as a duplicate, and continue the work in the other bug.

Thanks!
