Hi, I don't want to extend the old image rules. Take a look at rules/image-root-cpio-gz.make / platforms/image-root-cpio-gz.in
Duplicate this for xz. Or you could merge image-root-cpio and image-root-cpio-gz and add a choice for the compression mode (none/gz/xz). Unless someone can think of a use-case where both images are needed?
