Oddly enough, I was bitten by this recently, too, and had the same 
thing happen.  I upgraded a pool and was struck by the fact that I 
*wasn't* urged to update the boot code and so, after pondering "maybe 
this means I don't have to" decided not to.  Of course, the system 
wouldn't boot and I had to rescue it via a memstick.

I prefer the unconditional warning. :-)

Cheers,

Paul.
