This is always done at make time anyways. Why? I would imagine it to be useful to get immediate feedback whether changing the option was successful. It should be easy to run scripts/kconfig/conf -o on the config file afterwards. My normal workflow when changing single options is to remove the line from .config and call make oldconfig again. What I would like to see most here is something like ./scripts/config --reconfigure smp Remove SMP from .config, and do oldconfig to ask again. Arnd <><
