I suppose loader may have changed in some small way that is nevertheless significant. There's always the possibility that some benign bug may have become less than benign in unusual circumstances that the particular bootblocks contributed to. The explanation just doesn't fit either the theory, or most of the data points here. That doesn't mean the explanation is wrong, just that it will tend to be *regarded* as wrong. :-) -- Robert Nordier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
