+commit ce5a67127223e99ffdbf9cb697537c689e2fe364
+Author: Vincent Untz <vuntz@gnome.org>
+Date:   Tue Sep 25 10:55:31 2012 +0200
+
+    Fix same seat detection if built with systemd, but not booted with it
+    
+    If we haven't booted with systemd, then we can only assume it's always
+    the same seat.
+    
+    Based on patch by Takashi Iwai <tiwai@suse.com>.
