[Matthias Clasen <matthiasc src gnome org>]

commit b925c76ac7725283c45cfa9ab3cc8751c5e3b736

    Slave: add a marker file to request initial-setup
    
    The InitialSetupEnabled key in the configuration is now used
    to control whether the initial-setup feature is enabled at all.
    To actually run the initial-setup, you need to touch
    /etc/gdm/do-initial-setup.
