logind does that for you automagically™. The first seat has the rights to
poweroff or reboot the machine, and it can differentiate between local and
remote logins. You can check if your user session has the permissions to
poweroff/reboot via dbus:
$ gdbus call --system --dest org.freedesktop.login1 --object-path
/org/freedesktop/login1 --method org.freedesktop.login1.Manager.CanPowerOff
('yes',)
$ gdbus call --system --dest org.freedesktop.login1 --object-path
/org/freedesktop/login1 --method org.freedesktop.login1.Manager.CanReboot
('yes',)
But you need systemd to use logind1. There has been some attempts to
reimplement logind outside systemd, but I'm not sure how advanced they are.
This kind of problems were one of the reasons for creating logind.
