--- Comment #7 from C. Holm
You can not restart systemd-logind.service without loosing the login sessions!
Compare with bug #934901
Indeed systemd-logind can not do this. There is no serialize/deserialize feature built into systemd-logind.
Therefore zypper should *not* enforce this!
I wasn't suggesting a solution, just describing our workaround for the symptoms, to help locating the problem. (Since we usually experience this problem on servers, we can live with losing the login session, usually there aren't any long-lived ones. I can see how this would be a problem for GUIs, though.) (In reply to Dr. Werner Fink from comment #6)
It is simply that the running systemd-logind holds a lot of required data like file descriptors of sockets, devices, and some data more and if anyone enforce a restart then those descriptors are lost.
Therefore don't do this. I know it is nasty. Also I know that systemd its self can do a daemon-reexec and IMHO systemd-logind should have this feature as well. That implies that if upstream goes to implement such a feature the correct way would not to stop/start but to re-execute.
