Comment 6 for bug 638966

1) the --image_file created for use on a qemu system won't run on real hardware

How about "the --image_file won't run on qemu either" ? At the moment the kind of image produced by the --image_file option doesn't boot on qemu (it hangs trying to mount the rootfs), whereas if you fiddle the script to just generate the same image we would write to an mmc card this boots fine.
