Strange disklabel

[Anders Gytri]

The problem is resolved. I did a "dump, newfs, restore" and now the
disklabel looks more reasonable:

# disklabel da1s1
# /dev/da1s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  c: 2927171457        0    unused        0     0         # "raw" part,
don't edit
  d: 209715200        0    4.2BSD     2048 16384 28552
  e: 1048576000 209715200    4.2BSD     2048 16384 28552
  f: 1668880257 1258291200    4.2BSD     2048 16384 28552

I now consider this subject for closed.
