1) Download the discovery iso image, small size bootable is ok, no need to download the full image
2) mkdir -p /mnt/iso && mount -o ro,loop *iso /mnt/iso && mkdir -p /mnt/efiboot 
   && mount -o loop,ro /mnt/iso/images/efiboot.img /mnt/efiboot
3) optionally install web server if downloading from openshift mirror is slow. Assume the http root directory is /var/www/html, 
    curl -L -o /var/www/html/rhcos-live-rootfs.x86_64.img https://mirror.openshift.com/pub/openshift-v4/dependencies/rhcos/4.9/4.9.0/rhcos-live-rootfs.x86_64.img
4) install dnsmasq and tftp service. Assume tftp root is /var/lib/tftpboot
    /bin/cp -f /mnt/iso/images/*.img /var/lib/tftpboot
    /bin/cp -f /mnt/iso/images/pxeboot/{initrd.img,vmlinuz} /var/lib/tftpboot
    /bin/cp -f /mnt/efiboot/EFI/redhat/{shimx64.efi,grubx64.efi} /var/lib/tftpboot
