bluedevil rfkill

[Jonathan Riddell]

Hi David, I see you say:

Added support for rfkill, allowing to block Bluetooth (so that the Bluetooth
led lights off on some laptops) and also to unblock it.
This requires a read/write access to /dev/rfkill device and should be provided
by distributions.

could you explain to us distro packagers what rfkill is and how
distros can provide access to /dev/rfkill? (and why doesn't this have
a better interface through bluez?)

Jonathan
