Sometimes we'd rather avoid providing some of these "I don't trust this or that" options and impose some choices to users: "you need entropy to boot, stop being childish and collect the small entropy where it is, period". I'm not certain the other operating systems not experiencing entropy issues leave as many choices as we do. I can understand how some choices may be problematic in virtual environments but there are so many other attack vectors there that randomness is probably a detail. Willy
