Disable transmission-daemon on boot in Ubuntu 14.04 LTS

I realize that there are multiple posts regarding this. But most of them have to do with editing the program, which some people say is not a good idea. Then others talk about upstart, which is great, but I can't figure out how to use upstart to disable the application on boot. It definitely is an upstart application. I've been googling for about an hour, and cannot figure out the correct and supported way to do this.


This should work but you'll have to test it:

  1. Edit the config file for transmission-daemon:

    sudo vim /etc/default/transmission-daemon
    
  2. Modify the ENABLE_DAEMON value to 0:

    ENABLE_DAEMON=0
    

Now Transmission shouldn't start on boot.
