> When running "make config", an additional config.orig file is also
> generated, which is intended to hold the original, clean configuration
> from the template.
> When running make install, we first check if there is no existing
> .config file, and run make config if not. If there is a file, we then
> check if it's unmodified, in which case we regenerate a new .config to
> take account of any possible updates to the template. Finally, in the
> case where there is an existing .config file, and it HAS been modified,
> we then do a check to see if the template has had further updates, and
> throw an error if so. If no updates, we continue with the build using
> the existing, user-modified config.
