>Description:

	I was trying to optimize the filesystem layout for a HW
	RAID-5.

	'man 8 newfs' has the following section:

     -a maxcontig
                 This specifies the maximum number of contiguous blocks that
                 will be laid out before forcing a rotational delay (see the
                 -d option).  The default value is 8.  See tunefs(8) for more
                 details on how to set this option.

	While a '-d' option exists, there is no trace of it in the man
	page; in addition, 'man 8 tunefs' mentions neither the '-a'
	option (max. contiguous blocks' nor the '-d' option
	(rotational delay).

	There may be other places where the man pages are out of sync
	with reality.
 
>How-To-Repeat:
	
	Compare newfs(8) and tunefs(8) with the source code of the tools.

>Fix:

	Somebody with good ffs knowledge please sync newfs(8) and
	tunefs(8) with reality.
	At least newfs is a fairly critical tool, IMO.
