The CI stuff doesn't matter if that's the same since the CI images aren't exposed to the internet in any way that would make it matter. The normal install would have the same seeds of entropy, but diverge from there fairly quickly. The stuff that's used early in the install is the don't care sort of things that won't matter in the installer (which then creates it's own entropy that's different for every install). Warner
