Yesterday, my 10 years old son logged into my laptop running Debian jessie using his account, and curiously asked if he is allowed to try the /sbin/reboot command. Knowing I have a Linux system as opposed to some crappy Win machine, I replied "sure, go ahead and try". Seconds later I was completely shocked when the machine actually rebooted...
It's a feature. Users at the console can reboot, on the theory that if someone's sitting at the laptop they could also just push the power button...
If they were logged in remotely, they would not be able to reboot. Mike Stone
