2. Add "rng-tools" to the image for inputting entropy to the kernel - Speeds up initialization of nonblocking pool - On devices with HW random generator, this adds real entropy to the kernel pool - On devices without HW random generator, this adds bad entropy from /dev/urandom to the kernel poolHuh? Adding entropy from /dev/urandom back to /dev/urandom? This is worse than the "rob Peter to pay Paul" - you want to rob Peter to pay Peter.
It's a myth of some crazy tutorials and broken default configurations found on the internet. Don't do that!
By the way, it's strange that the entropy is emptied just after boot (which is when there should be plenty of I/O to refill the entropy pool).
