+Subject: [PATCH] change sysconfig path to /etc/default
+
+OE uses /etc/default for service configuration, not /etc/sysconfig which
+is used by SUSE and RedHat based distributions.
+
+Change the files accordingly
+
+Upstream-Status: Inappropriate [OE specific]

+Subject: [PATCH] add WantedBy directive to btrfsmaintenance-refresh.service
+
+Just trigger the service on the first boot, to configure services to the
+configuration file deployed in the package, afterwards disable the
+service, so that is only triggered when the configuration file has
+changed.
