Once you do a "rpmbuild -bp kernel-xxx" you get a ready to build tree in
/usr/src/redhat/BUILD/kernel-xxx. In the linux-xxx/configs subdirectory
(_and_ in /usr/src/redhat/SOURCES) you will find the configuration files
(*.config) that are used by the spec file to build the kernel. If you
know exactly which configuration options you want to remove you could
edit the file that corresponds to the architecture you are building for
(for example: kernel-2.4.22-i686.config), manually change the options
and store that file in /usr/src/redhat/SOURCES. Or you can manually copy
that file into the BUILD/kernel-xxx/linux-xxx/.config file, run "make
xconfig" (or whatever you prefer), save the configuration and then copy
it back to /usr/src/redhat/SOURCES with the proper name. If you now do
an "rpmbuild -ba kernel-xxx" the build will use the modified
configuration file.
