Yes, that's exactly how Phase I (400 nodes) and Phase II (600 nodes) were
done. In Phase III (~ 1056 nodes), the scalable unit does not include a
machine with a disk. So the kernel image is downloaded from the mother in
each unit, but the root disk for all 1,024 nodes is served by the
super-mother, which is just one machine.
