If unsure, say N. >From a user perspective, I believe it should say "If unsure, say Y". The unsure case for the unsure user should be the case that works for the broadest possible usage spectrum, which would be the 'Y' case. To put it another way, if you pick 'Y' and don't really need it, the only downside is wasting some memory. But if you pick 'N' and actually did need it, previously working IPv6 networking would no longer work. I believe the default setting should match the unsure recommendation. -Bill - 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/
