+Subject: [PATCH] Fix some problems in the systemd code
+
+The stop and restart functions forgot to pass the manager
+object down, and then tried to emit signals on a NULL
+object. Also, we were unreffing a variant that was NULL
+half the time. Don't do that.
+
+Fixes the problem where a poweroff request in the presence
+of multiple user sessions leads to a PolicyKit dialog that
+comes back every time it is canceled.
