I upgraded a pool and was struck by the fact that I=20 *wasn't* urged to update the boot code and so, after pondering "maybe=20 this means I don't have to" decided not to. Of course, the system=20 wouldn't boot and I had to rescue it via a memstick. I prefer the unconditional warning. :-) Cheers, Paul.
