+                    By default, the service is enabled to automatically start
+                    at boot time.
+                    The default setting is in the

+                    When you specify this file in your recipe, use a package
+                    name override to indicate the package to which the value
+                    applies when the value applies to a package other than
+                    the recipe's main package.
+                    Here is an example from the connman recipe:

+     SYSTEMD_SERVICE_${PN} = "connman.service"
