    sbin/sunlabel        sunlabel.c 
  Log:
  - Use read(2) to get the existing sunlabel on a disk, instead of parsing
    kern.geom.conftxt, which md disks don't show up in.  If the magic and
    the checksum are right assume its a valid sunlabel, otherwise use the
    DIOC ioctls to get the disk parameters and whip up a label out of thin
    air.
  - Don't just silently create or correct invalid c partitions, warn about
    invalid ones in label proto files.
  - Split checksumming into a function since we do it a couple times.  Also
    don't include the sl_cksum field in the checksum, which avoids needing
    to clear it first.
  
  This is makes sunlabel a suitable replacement for disklabel in make release.
