The main reason I recall the suggestion coming up is that, due to
IPv4 address starvation in some provider regions, nova boot was
taking an hour or more to return waiting for an IP address to be
assigned. Using nova rebuild would have supposedly avoided the
address churn and thus improved instance turnaround for us.

There may also have been other reasons for recommending rebuild to
us, but if so I don't recall what they were.
