so, the config file works over & over? even for different kernels?
Not exactly, but almost. When a new kernel is released, you can reuse most of your old .config by copying it into your Linux source top-level directory and running 'make oldconfig'. This answers the long list of configuration questions automatically, using your old settings, except for options that disappear (features that change, or are dropped entirely, in the new version) and options that are new. For the new options, you'll have to manually provide an answer -- most often (but not always!) the default option is what you want, and you can simply hit <Enter>.
