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):

systemd-222-13.fc23.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Go to unprivileged shell prompt.  Type reboot.  Hit enter.
2.
3.

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.
