Match only devices which udev has set up already. This makes
sure, that the device node permissions and context are properly set
and that network devices are fully renamed.
</p>
<p>
Usually, devices which are found in the kernel but not already
handled by udev, have still pending events. Services should subscribe
to monitor events and wait for these devices to become ready, instead
of using uninitialized devices.
</p>
<p>
For now, this will not affect devices which do not have a device node
and are not network interfaces.
