But I assume that won't be a big deal either. By the way, I'm curious: as we do this virtualization step-by-step, is there any way for userspace to tell how far we've gotten? So for example if you have a system that's configured to use some new namespace-based feature, and you boot it to an old kernel, is there some way for it to check at the start and say "sorry, this isn't going to work"? --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
