I'd still like to look at the sources for these scripts, if anybody knows
where they are located, I have not had any luck locating the sources
for oldconfig and the

All good to know; the more reason I probably need to read those scripts,
as I roll out my (ansible) codes for using one bank of hardware to 
setup and boot a variety of different cluster and container configurations.

I thought they might be in /usr/src/linux/scripts/ but no? No hints in the
top level Makefile either. One of the Gentoo GSoC projects is to rework 
kernel building too. Now I'm stoked to read the scripts/makefile for
oldconfig and such....
