  If you build a cpio rootfs, you shouldn't need any additional command line
parameters because the kernel never gets to mounting the root filesystem.  It
just runs the /init in the initramfs.

  Using a cpio rootfs should also solve your problems with the device nodes,
because we provide a /init that mounts devtmpfs explicitly.
