    I'm not sure what is going on with Grub but note that I changed he
    disklabel for DragonFly as well.  Well, not precisely changed it, more
    like a natural extension to support up to 16 partitions instead of 8.

    DragonFly should still be able to mount non-extended partition tables,
    so maybe FreeBSD did do something to the disk label... maybe GEOM-related.
