[plug] Accidental reboot

I have a number of machines I routinely use, and a number of virtual 
machines inside those. I've lost count of the number of times I've run 
"sudo reboot" thinking I was logged into a guest and taken down the host 

I've tried all sorts of tricks with /sbin/reboot and /sbin/shutdown to 
try and stop me doing dumb things to no avail.. then this afternoon it 
hit me.

The system's path is :/bin:/sbin:/..so on

Every user (including root when using an interactive shell) has the path 
prepended with /usr/local/bin.

Put together a quick /usr/local/bin/reboot
echo Surprise!

Problem solved. Why did it take me so long to think of it?
