I think the redhat people who are working on this are getting the most
benefit from a large disk read-ahead, prior to the main services being
started. If that accounted for the majority of speed-up, maybe it alone,
and not a fragile parallel boot process too, would be sufficient for
most people in need of a more efficient boot.
