Note that this fake data is the hardest to gather entropy from, as it doesn't interact with any external hardware. I'm all for testing it on real hardware and I expect to be able to gather even more entropy from it (so discarding less than top 7 bits). The problem with making observations during boot takes much, much longer, so it will limit the number os samples significantly, and as you know the more samples the better. -- Pawel Jakub Dawidek http://www.wheelsystems.com FreeBSD committer http://www.FreeBSD.org Am I Evil?
