We've been very lacks in checking the disk label as witnessed by the fact that sysinstall creates faulty labels and we didn't even know. The message can go away (or put under boot verbose) when the dust settles. > I don't see why FreeBSD is making such a mess of geometries with > modern SATA/IDE disks. We seem to be the standout here. :-( We've never treated it seriously. We keep saying "it doesn't matter with modern disks" and things like that and as such side-step the issue that file systems or disk labels still record them, use them or need them. We created the problem ourselves by creating inconsistency at various levels. With geom_part I made it more visible so that we can actually make it better. -- Marcel Moolenaar xcllnt@mac.com
