Hacker news discussion where cperciva does not disagree with "Myths about /dev/urandom"
https://news.ycombinator.com/item?id=10149019
The risk of using urandom is that it can be deterministic.
If you know the seed, you may know all of urandom's output forever.
That is why we prefer to add entropy at runtime, using e.g. haveged.
But does haveged affect urandom? The urandom seed may be set just
once and saved, or set at boot before haveged runs.
