How do you have bluetooth off at boot?

view story

http://forums.fedoraforum.org – In F17 with Gnome3 my laptop boots with Bluetooth enabled. I would like to have bluetooth off when the computer is turned on, but still available for use if I want it. A simple systemctl disable bluetooth.service does not stop bluetooth from starting and being on. I notice there is a bluetooth.target as well, and reading http://fedoraproject.org/wiki/Systemd it is stated as an example under the definition of targets: "bluetooth.target which is requested as soon as a bluetooth dongle becomes available and which simply pulls in bluetooth related services that otherwise would not need to (HowTos)
