No, ``disklabel ... auto'' doesn't create any (valid) slice. It creates a bogus 4th fdisk entry, ``since this used to be so all the time'', and since Bruce's slice code expected something like this (IIRC) in order to accept the disk as a ``classic one'', i.e. one without slices. I hope Mike's changes don't start to unsupport non-sliced disks... I know of quite a number of people who'll scream then. All this mess started with the advent of the slice code in FreeBSD 2.0.5, and with the suggestion ``If you fail to install FreeBSD because of geometry problems, then well, install a small DOS partition first.'' That's simply plain unacceptable (and looks very unprofessional, too), and the intention behind my ``dangerously dedicated'' mode sysinstall changes were simply to support the class of people who Just Don't Care about any f*****ing fdisk table at all (since they don't need it, all they need is a disklabel). Note that ``sd2e'' could have two different meanings by now: it was the partition `e' on the ``compatibility slice'' iff the disk has a valid fdisk table. Alternatively, it was the partition `e' on a disk without an fdisk table. Sorry, i haven't been following -current too close lately, just returned from a vacation. So i don't know the exact details of Mike's changes, i'm just walking through tons of email. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
