(In reply to Ludwig Nussel from comment #29) There is no workaround even IgnoreOnIsolate=yes in all slices does not help as you can imaging by reading ttps://github.com/systemd/systemd/issues/1969 and the cited commit https://github.com/systemd/systemd/commit/417800228f69db9ff37f4193d11508757dd09308 therein. Only reverting https://github.com/systemd/systemd/commit/8c8da0e0cb498245c765732cf9caa081a70c560f may help. Maybe I should do like upstream and close this as RESOLVED with solution UPSTREAM as this bug is introduced at Sep 29, 2015, had been reported at on Nov 20, 2015, but has not been fixed since (Feb 18, 2106). Btw: I really wonder *why* QA had not found this glitch.
