freebsd stable - Jul 2009 - MAKE_DVD=1 make release

I'm not seeing a way to make the dvd image with:

# $FreeBSD: src/release/Makefile,v 1.924.2.9 2009/04/15 03:42:59 kensmith Exp $

Am I missing the proper way to do this?
Or can someone commit 'MAKE_DVD=' into 'MAKE_DVD+=' on lines 195
and 225?
Or commit a more suitable update to src/release/Makefile?
Thanks.

Oops, DVD is made by default.
I was reading '.if defined(MAKE_DVD)' as 'if not null', not
'if defined'.
I retract this errant report :)
The one about NO_FSCHG is still good though.
