Expected behaviour you didn't see

If only one user is logged in and he runs "run0 systemctl reboot" or "run0 systemctl soft-reboot", this should succeed as if the user would have logged in on console as root.

Unexpected behaviour you saw

User is logged in on pts/0. Please retry operation after closing inhibitors and logging out other users. 'systemd-inhibit' can be used to list active inhibitors. Alternatively, ignore inhibitors and users with 'systemctl soft-reboot -i'.

Steps to reproduce the problem

ssh to a remote server as normal user no other user is logged in try to reboot with "run0 systemctl reboot" or "sudo systemctl reboot", or become root with "su".

Additional program output to the terminal or log subsystem illustrating the issue

User <user> is logged in on pts/0.
Please retry operation after closing inhibitors and logging out other users.
'systemd-inhibit' can be used to list active inhibitors.
Alternatively, ignore inhibitors and users with 'systemctl soft-reboot -i'.
