What's the possibilities of recycling /usr/obj for other targets, etc?

[Chris H]

Greetings all,
 I've been combing /usr/src, build, relese, and
release engineering in the FBSD docs, for the last
couple days. But still haven't *quite* unwound everything
in src. What I'm attempting to do, is to recycle a recent
build/install world/kernel I still have in /usr/obj.
To create
1) a utility CD/DV
2) a [minimal] "release" CD/DVD
I'm *sure* I'm just over-complicating things. But
it's still unclear as to whether any of the already
available targets/dists -- release, distribute,
distributekernel, distributeworld. Will attempt to
REbuild world && kernel, before proceeding. If I'm
not mistaken -DNO_CLEAN (might?) help me coerce make to
do my bidding. Or is only available to speed up the
initial build, after a
cd /usr/obj
chflags -R noschg *
rm -rf *

Any help, pointers, suggestions, ... *greatly* appreciated.

BTW I'm attempting this on a recent -CURRENT (11).

Thanks!
