I think that is only true for some old stuff in old systems. I believe I saw somewhere that it only is meaningful it the -A option is used. It might also be meaningful for the so-called 'dangerously dedicated' disk where you don't use a slice, but the raw drive. But, I never start it at an offset of 16 - always 0 if my partition is within a slice. ////jerry > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
