If .config exists, "make oldconfig" will use that.


If you are copying a config file to start from, why would you do a "make oldconfig"?


You wouldn't need to. Under stock kernels, "make oldconfig" will ask you for the settings you'd like, individually. Under Red Hat's patched kernels, "make oldconfig" will try to find a prepared config that matches your arch, indicated by /boot/kernel.h. In either case, if .config exists, then you'll only be asked about new configuration items (which there should not be any of, if it uses one of the prepared configs).
