 I'm afraid several other ports also have the similar issue
 (i.e. no on-disk bsddisklabel data, but the kernel converts
  their native OS labels to bsddisklabel in readdisklabel(9)).
 
 - sys/dev/sun/disksubr.c:
   disklabel_sun_to_bsd() converts SunOS label
 - sys/arch/amiga/amiga/disksubr.c:
   readdisklabel(9) handles RDB
 - sys/arch/atai/atari/disksubr.c:
   ahdi_label() converts AHDI label (optional)
 - sys/arch/luna68k/luna68k/disksubr.c
   disklabel_om_to_bsd() converts UniOS lavel (similar to SunOS one)
 - sys/arch/mac68k/mac68k/disksubr.c:
   read_mac_label() converts Apple Partition Map
 
 I have not checked if writedisklabel(9) always writes
 BSD disklabel or converted one in all cases, though..
