>Organization:
Idiom Consulting
>Environment:

	I have a 7200 rpm disk.

>Description:

	I would have liked an opportunity to provide newfs parameters
	at install time.  

	There are a couple things I like to do: rotation, inodes, and 
	minfree.  If I knew how to choose a maxcontig, I would probably
	want to set that too.

	Also, I found a bug in NetBSD's newfs -- there is some chance it's 
	in FreeBSD's newfs too: if you specify -m 0 -o time, the -o time
	is ignored: "Warning: changing optimization to space because 
	minfree is less than 5%."

>How-To-Repeat:

>Fix:
	Well, since 2.0.5 sysinstall you can.  Closed this.
	BTW: the entire rotational optimization ought to be pulled
	and as default it has been disabled since it actually degrades
	performance on moden track-caching disks.
