"fdisk" is optional if the disk isn't to be booted from.

The command is "newfs", but first you have to make the partition type
into "4.4BSD", and set the fsize, bsize, and cpg parameters. For example:

4 partitions:
#        size   offset     fstype   [fsize bsize   cpg]
  a:  4198257       63     4.2BSD     4096 32768    96   # (Cyl.    0*- 4164)
  b:  8396640  4198320     4.2BSD     1024  4096    32   # (Cyl. 4165 - 12494)
  c: 12594897       63     unused        0     0         # (Cyl.    0*- 12494)
  d: 12594960        0     unused        0     0         # (Cyl.    0 - 12494)

You can do that with...

	disklabel -W wd0
	env EDITOR=vi disklabel -e wd0
	disklabel -N wd0

["wd0a" is my "/usr", and wd0b has the NetBSD cvs'd sources.]

Now, "newfs" only picks up the fragment size and block size from the
disklabel -- it seems to ignore the cylinders per group -- so to
actually make a file system with custom parameters you'd have to
specify "-c", as, for example, "newfs -c 96 /dev/rwd0a". [If you want
to stick with the defaults, they're "1024 8192 16".]
