The third step does this, with the addition of a comment line at the top
of the file that's needed for the rpm build to work:

(echo "# $(uname -i)"; cat .config) >
~/rpmbuild/SOURCES/kernel-2.6.15-$(arch).config

I didn't want to do that because I thought a tweaked kernel *should*
have a different name from the stock one. I know the kernel maintainers
get very upset at bugzilla reports about tweaked kernels that purport to
be stock kernels.

Is there some problem that needs the kernel to look exactly like the
stock one for yum?
