  I've decided to extend coverage of g_bsd instead of creating g_nbsd just
because this route is shorter (I think that layout differences between
disklabels in FreeBSD and NetBSD are not so big that would justify that
piece of work and code duplication). After all, I think that NetBSD people
were forced to extend their label just by the fact that they don't have
slice units, and in most setups there will be enough 'a'-'h' entries
to describe NetBSD partitions. In my example:

#        size    offset     fstype [fsize bsize cpg/sgs]
  a:   2097648 147942585     4.2BSD   2048 16384 21872
  b:   2097648 150040233       swap
  c:  81931500 147942585     unused      0     0
  d: 312579695         0     unused      0     0
  e:   2088387        63      MSDOS
  f:  61440624 152137881     4.2BSD   2048 16384 28704
  g:  10150560 213578505     4.2BSD   2048 16384 28456

it would be useful to move 'e' partition to the unused entry after 'h' (e.g.,
'm' or 'n'), then it'll be available for the NetBSD partition. I think 'a'-'h'
partitions are well enough for easy data interchange between NetBSD and 
FreeBSD.

  And, after all, I we call something 'g_bsd', we imply that it should 
understand all BSD's layout (including NetBSD), aren't we? (this is just
my impression and hardly a technical argument ;)

Sincerely, Dmitry
