Whether to allow any user to lock the screen. This will install a
38
+
setuid wrapper to allow any user to start physlock as root, which
39
+
is a minor security risk. Call the physlock binary to use this instead
40
+
of using the systemd service.

Note that you might need to relog to have the correct binary in your
43

PATH upon changing this option.
