How to Set Bluetooth Off by Default On Linux (Ubuntu 10.10)

If you want to save power, likely make your laptop more secure, and you do not use bluetooth all the time then why not have it disabled by default and still be able to turn it on using all the usual methods. If you are using Linux then all you have to do is to run “rfkill block bluetooth” at start-up. To do this add the line to an existing file (I already had a file named bluetooth, so I used that) in /etc/init.d/ or create a new file with that line.
