Well at least for Amazon, what is there is what we (Fedora) push up,
so it's all Fedora now, with our own kernel.
I am sure Max Spevack and Justin Forbes can speak to this more
intelligently than I can.
I don't have visibility into a lot of the public clouds. I do get the
impression that RackSpace uses their own kernel or at least has
historically. For some of the others, I know they aren't rolling their
own kernel, they are booting what ships, creating templates of it etc.
