This is more than a bit hard to test, requiring as it does an actual
iLO BMC, so sadly I have no tests :(.
HP Hardware really wants to be running latest firmware, and its
commonly agreed that one place where it can be sanely applied is in
the deploy environment, so this is my long threatened implementation
of that.
