    Use systemctl runtime mask to prevent automounting (#701676)
    
    With the beta release of Fedora 19, invoking gparted appears to
    automatically mount partitions.  The systemd daemon appears to be
    performing the automounting.  Hence use systemctl runtime mask to
    prevent this automounting from occurring.
    
    Bug #701676 - gparted doesn't inhibit systemd mounting, leading to
                  potential data loss
