I don't have GEOM_PART in my kernel, but if you said it's default it
should be pulled in.

But why :

# /dev/md2s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:  10m       16    4.2BSD        0     0
  b:  10m       *    4.2BSD        0     0
  d:  10m       *    4.2BSD        0     0
  e:  10m       *    4.2BSD        0     0
  f:  10m       *    4.2BSD        0     0
  g:  10m       *    4.2BSD        0     0
  h:  10m       *    4.2BSD        0     0
  i:  10m       *    4.2BSD        0     0
  j:  10m       *    4.2BSD        0     0
  k:  10m       *    4.2BSD        0     0

  c:  2047973        0    unused        0     0         # "raw" part, don't edit

line 11: partition name out of range a-h: i
line 12: partition name out of range a-h: j
line 13: partition name out of range a-h: k
re-edit the label? [y]:

I'm on 8.1-RELEASE.

Cheers,
