To clarify - the jitter entropy question was related to that same basic issue: if this was meant to be a way to mitigate the lack of jitter entropy on some platform you care about, that would again possibly be a reason to care. Considering that we apparently haven't cared for the last 7 years, I'm still a bit surprised, but whatever. What I *don't* want is just more voodoo discussions about /dev/*random behavior that doesn't have a technical reason for it. Linus
