Hi, we use those images (the root.tar.gz) ones for diskimage-builder in OpenStack. We build both vm and baremetal images from them, and currently assume that there is a kernel in them (but we do remove grub from them early on). Overall I think this is probably a good idea, but we'll need to fixup our code to be a bit more explicit about whether the output is for a vm or physical machine.
