Hmm, is this commit included in openSUSE-SU-2017:0907-1?

Sure, but that doesn't work because a "snapper cleanup number" then says "quota
not working (preparing quota failed)". I had to manually assign the correct
qgroup to the snapshot subvolumes already taken without an qgroup. snapper only
did this automatically for the first snapshot without an qgroup. Took me an
hour to figure that out...
