Commit Message

start-stop-daemon starts udevd in the background and returns before
udevd listens to kernel events. The coldplug events generated right
after by "udevadm trigger" may then get lost, so that no module is
loaded at boot:

  Starting network: Waiting for interface eth0 to appear............... timeout!

Wait until udevd answers on its control socket before triggering the
events.

Fixes: 41258a81948fddfa7fc8ac06b69d77fa051b744d ("package/eudev: refactor init script and rename it to S10udevd")
