I just migrated :-) Took half an hour without internet and I had to fix stuff multiple times during the process in parallel on router and in repo, but should be working. Will try to retest tomorrow before the meeting. The not so nice part is that console is polluted with mmc error messages when using USB, need to consult with kernel guys later.
Do not review 338fc261, we already spend month arguing about that one.
