Subject: [PATCH] Add udev mode to bluetoothd
|
||||
|
||||
Add --udev option to bluetoothd, to allow it to be started on-demand
|
||||
from udev.
|
||||
|
||||
When a new adapter appears, udev would launch bluetoothd --udev.
|
||||
|
||||
To avoid problems with udev, bluetoothd --udev would only return
|
||||
an error exit code if it wasn't already running and a real error
|
||||
occurred.
|
||||
|
||||
When no more Bluetooth adapter are present on the system, bluetoothd
|
||||
will exit after a 30 second timeout.
