Alan Jenkins 1d422b153b units: order service(s) before udevd, not udev-trigger (coldplug)
Since hotplugs happen as soon as udevd is started, there is not much sense
in giving udev-trigger an After= dependency on any service.  The device
could be hotplugged before coldplug starts.

This is intended to avoid the race window where we create the hwdb with
the wrong selinux context (then fix it up afterwards).
