Subject: [PATCH] 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
