        that it can be uninstalled without breaking the system
      + Add unity-session
    - Split ubuntu-session out of gnome-session.
    - Add upstart user session and systemd user session:
      debian/data, debian/gnome-session-bin.user-session.upstart

       Moved registering gnome-session binary as a session manager to
       gnome-session-bin package
    - Add gnome-session-wayland transitional package
    - don't install gnome-mimeapps.list (installed by desktop-file-utils in

      gnome-session-common.maintscript, gnome-session-common.postinst
