I think there's a small misunderstanding here, my understanding is that for quite a while, the possibilities offered by the various random subsystems or their proposed derivative used to range from "you have to choose between a fast system that may be vulnerable to some attacks, a system that might not be vulnerable to certain attacks but might not always boot, or a slow system not vulnerable to certain attacks". Greg's point seems to be that if we add an option, it means it's yet another tradeoff between these possibilities and that someone will still not be happy at the end of the chain. If the proposed solution covers everything at once (performance, reliability, unpredictability), then there probably is no more reason for keeping alternate solutions at all, hence there's no need to give the user the choice between multiple options when only one is known to always be valid. At least that's how I see it and it makes sense to me. > And this is all ??? Possibly a lot of people got used to seeing the numerous versions and are less attentive to new series, it's possible that your message will wake everyone up. Regards, Willy
