Many thanks for your help!

That's what I thought I did. And yes, it is included. I didn't find it because
the changelog is not ordered by date. First entry date is 2017-02-19 and last
2009-03-04. However, the record you mentioned is dated 2017-03-27 and found in
line 36776?!

Me too! I already noticed that I was not able to re-enable them in Comment #29.

Maybe https://github.com/openSUSE/snapper/issues/257? Because of this issue, at
least the exception message "preparing quota failed" was added in
https://github.com/openSUSE/snapper/issues/259.
