Therefore, re-seeding it from another seeded DRNG (i.e. the nonblocking > pool after it is initialized) may not give us too much extra. My main concern with your original approach was precisely the fact that get_random_bytes may be called before the before the kernel pool is ready. So Ted's solution solves that perfectly. Please do what Ted says and we can all move forward.
