-# This 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.
-#
-# If needed, to work around broken or non-hotplug-aware services,
-# it might be enabled unconditionally, or pulled-in on-demand by
-# the services that assume a fully populated /dev at startup. It
-# should not be used or pulled-in ever on systems without such
-# legacy services running.
+# This service can dynamically be pulled-in by legacy services which
+# cannot reliably cope with dynamic device configurations, and wrongfully
+# expect a populated /dev during bootup.
