Bug#803907: systemd: Unable to shutdown/restart because of 'nobody' session

[Nikolaus Rath]

Package: systemd
Version: 215-17+deb8u2
Severity: normal

Dear Maintainer,

I would like to restart my system, but:

$ systemctl poweroff
User nobody is logged in on ???.
Please retry operation after closing inhibitors and logging out other
users.
Alternatively, ignore inhibitors and users with 'systemctl poweroff -i'.

Upon closer investigation:

$ grep nobody /etc/passwd
nobody:x:65534:65534:nobody:/nonexistent:/usr/sbin/nologin
$ ps -U 65534
  PID TTY          TIME CMD
 7701 ?        00:00:00 systemd
 7702 ?        00:00:00 (sd-pam)


I don't know what exactly this systemd process is doing, but I
did not start it, and I can't imagine that it does anything useful.
