Oddly enough, I was bitten by this recently, too, and had the same=20
thing happen.  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.
