Bluetooth can be problematic. Some systems use Bluetooth to communicate with their keyboards and mouses. AFAIU, that is one of the reason why most Bluetooth enabled systems will always powerup the radio during first stage of the boot process, so one with a Bluetooth keyboard can reach firmware settings. I was thinking something like "yeah, we could have a checkbox in the greeter", but many laptops have an hardware kill switch these days. In any cases, blocking GPS by default sounds like a good plan. -- Ague
