+# Purpose : helper script for rpm scriptlets to remove a
+# systemd unit.
+#---------------------------------------------------------------
+
+# Reload systemd configuration and try to restart units
+# It has to be done in postun because package removal may delete
+# some links and we need to inform systemd about it
