    Isn't there some sort of a circular dependency going on here? As I
    understand it the vmlinux binary already contains the initramfs as
    built-in data (at least that's what I use here for initramfs). It
    makes more sense if you guys are creating an _initrd_ image (that's
    what mkinitrd originally did AFAIK) and supply it to the boot-loader.
