Specifically, you either have an "all disk slice", or you have an "historically bogus slice entry". In the first case, fdisk will show slice 1 covering the entire disk. In the second case, fdisk will show slice 3 containing 50000 blocks (24MB). > 2. My kernel is built with "root on wd0a" This is ignored. > 3.

Which "identity"? The disk type (ESDI is what you get for IDE disks) or the 'disk:' field (which is almost certainly correct). > So, as a "dangerously dedicated" kind of guy, what do I need to do in the > brave new world of "Slices uber ales?" Update mount. Follow its recommentations. You may find that you have a sliced disk after all, in which case regardless of what you think you want, what you have is what you have. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
