+Subject: [PATCH] build: add a gnome_session_ctl_path option
+
+In gsd.service.in the ExecStopPost expects g-s-d libexecdir to
+be from the same prefix as gnome-session's, and this is not necessarily
+true as there are linux distro's that install their packages into their
+own individual prefixes (like NixOS or Guix).
