Numerous modern day basic-intent CPUs also have hardware random quantity generators. This helps a lot with this issue. The best practice is to gather some entropy in other means, continue to retain it in the random seed file, and mix in some entropy in the components random selection generator.
Our suggestion is to gather randomness in the course of the entire set up from the operating process, preserve that randomness in a random seed file. Then boot the process, gather some extra randomness during the boot, combine in the saved randomness with the seed file, and only then produce the host keys.
