This barrier service is usually not enabled by default. If enabled,
it acts as a barrier for basic.target -- so all later services will
wait for udev completely finishing its coldplug run.
It might be enabled just unconditionally, or pulled-in on-demand by
broken or non-hotplug-aware services that assume a fully populated
/dev at startup.
