Bug

Hi ! ignition file is not mounted with qemu if we use opt/com.flatcar/config as key name for the firewall configuration. (as suggested in the doc: https://docs.flatcar-linux.org/os/booting-with-libvirt/#running-flatcar-linux-on-libvirt). We need to use opt/com.coreos/config. We need to fix the documentation or the const value. (I don't know what is the best)
