on 1.3F/i386:

5 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:   204624        0      4.2BSD     1024  8192    16   # (Cyl.    0 - 202)
  b:   122976   204624        swap                        # (Cyl.  203 - 324)
  c:  1065456        0      unused        0     0         # (Cyl.    0 - 1056)
  d:  1065456        0      unused        0     0         # (Cyl.    0 - 1056)
  e:   737856   327600      4.2BSD     1024  8192    16   # (Cyl.  325 - 1056)

So, what is so bad about having an offset of 0? As long as you really want
the whole disk given over to NetBSD, this isn't a problem, is it?
