systemd-logind crashed with SIGSEGV

[Jeff Lane ]

Dunno, I went away and came back to this. What I can say was that Landscape was supposed to reboot this machine while I was away, and it appears that the Landscape triggered reboot never happened.

Perhaps this systemd failure is a symptom or the reason that the reboot failed to occur as scheduled.
