David wants it to be for developers (ISTM) and "select" is a hassle for us. Linus wants it to be for (unadvanced) users, but they tend to just use distro kernels and distro configs, according to David, and I agree with that. So I think that make *config is more for developers and advanced (not embedded) users. > As an example of this, look at SATA.

It's a real problem for developers who actually try to modify configs. --- ~Randy - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
