Another update on Fedora infrastructure

There's a diversity argument too. If everyone's infrastructure relies on RSA exclusively and
then next week someone finds a serious problem in RSA then you've got a massive disaster.

Which doesn't add up to an argument for DSA, but it does mean it's not enough to say "RSA is
better, we'll just use that". We know that RSA is no /harder/ than the factorisation problem,
but we don't have a proof that it isn't /easier/ perhaps /much easier/. We must have
alternatives, maybe Elliptic Curve or maybe something quite different.
