Right. If I take my .config, get just non-"n" entries, get rid of the CONFIG_ at each line, then gzip(1) the result, I get 1515 _bytes_. Less than the rounding error in a module, can be expanded on the fly with existing infrastructure.
Sure, it makes sense to have .config around somehow for some rather specialized cases, but kludgeing on some such functionality for a very niche use just stinks, IMHO. -- Horst von Brand http://counter.li.org # 22616 - 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/
