Description David Howells 2016-02-02 05:56:20 EST
Description of problem:

I found out by accident that the 'reboot' command can now be run by an unprivileged user - you don't need to be root to use it.

One thing I don't know is whether this user needs to be the user you're logged in as.

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1.Go to unprivileged shell prompt.  Type reboot.  Hit enter.

Actual results:

System reboots

Expected results:

Should get an error message telling me that I don't have sufficient privilege for this.  System should not reboot.

Additional info:

I have /usr/sbin in my path because that directory contains some useful programs that can be run as an unprivileged user - wireshark for example.
Comment 1 Zbigniew Jędrzejewski-Szmek 2016-02-02 08:10:07 EST
Yes, it's intentional. Users logged in at a physical console get a right to reboot the machine. This is done through policykit, see /usr/share/polkit-1/actions/org.freedesktop.login1.policy. You can always override this setting locally.
Comment 2 David Howells 2016-02-02 09:24:23 EST
This seems to show the right way to override it:
