I was looking at it like I do for connman, where it will start even if there isn't any network interfaces currently available and that is expected behavior to me. Bluez could be waiting on a usb bluetooth adapter to be added just like connman is waiting on a usb ethernet adapter (and it isn't obvious to my that this is taking up a much in the way of resources or adding a lot of wakeups but I don't know). Either way I expect an easy to turn on and off UI component making either default simple to correct. Right now, the connman UI I am using just presents a bluetooth option for enable/disable but it doesn't work as is without the service being able to autostart without being enabled manually (or by the distro default). -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
