I was able to make it work but not with my configuration above. It looks like I can use a type of "fsimage" for my "ROOT" partition, but I have not been able to figure out the syntax there yet. For "BOOT" I am at a complete loss. In theory "bootimg-efi" but there doesn't seem to be a way to provide an initramfs.
