Works for me! root@precipice$ disklabel /dev/sd1d disklabel: /dev/sd1d: Invalid argument root@precipice$ disklabel sd1 disklabel: ioctl DIOCGDINFO: Invalid argument However, I was very wrong about the disk never having a label. It used to be my old root drive, and I think a FreeBSD 1.1 label might still exist having not been overwritten, even though the entire disk is now a DOS drive... this leads me to wonder... sd1s1: start 32, end = 819199, size 819168: OK sd1s2: start 819200, end = 2041855, size 1222656: OK sd1s5: start 819232, end = 2041855, size 1222624: OK > 2) All of this slice stuff is really verbose and I think gratuitous. > Note: I am using older boot blocks that don't support -v, so it Agreed! > 2) When the system is booting, it whines loudly about partitions not being > inside slices... this may indeed be an error condition, but that's the > way FreeBSD 2.0 did things, so you're going to have a hell of a support > problem with these new slice changes. Agreed again. We're going to need to deal with this somehow, or users are going to SCREECH. Bruce is safe over there in OZ, but I know that folks like Poul and I are going to get hundreds of mails in our boxes! :-( > 3) Oh where oh where has my MSDOS partition gone? Oh where oh where > can it beeeeee? Try copying the new MAKEDEV over and doing a ./MAKEDEV sd0, then try: mount -t msdos /dev/sd0s1 /dos Assuming, of course, that slice 1 is the DOS partition. This is actually a very GOOD part of the change and I'm happy that we have it. It will make auto-detecting and mounting the DOS partition from the install much easier (I can just look to see what partition is a DOS partition and then mount the corresponding slice). I'm a little fuzzy on something, what is a slice vs a partition? Is a slice one of the one of four (recursive) classic DOS partitions or is a slice a UNIX disklabel partition?
