commit 2fe566e35da34d52d0380407f2ab8bbd65a682cd
Author: Iain Lane <iainl gnome org>
Date: Wed Jul 4 11:50:09 2018 +0100
Add a gnome-session-systemd binary to launch the session
This replaces the shell script, and is responsible for uploading the
environment as well as cleaning up if any previous sessions left units
in a failed state.
