Lots of present day typical-goal CPUs even have hardware random amount generators. This allows a lot with this issue. The ideal apply is to collect some entropy in other approaches, continue to preserve it in the random createssh seed file, and mix in some entropy from the components random range generator.

Our advice is to gather randomness in the course of the whole installation of the running system, help save that randomness in a very random seed file. Then boot the technique, gather some far more randomness during the boot, mix within the saved randomness through the seed file, and only then crank out the host keys.
