Hi Linus, This seems like a pretty nice idea. It seems like a lot of small embedded boards are fairly deterministic and have lots of identical board information, with possibly the only thing differing board-to-board on firstboot being whatever serial number is baked into the SD card. And the input pool only ever accumulates with add_device_randomness(), so in the worst case, this won't hurt anything. So: Acked-by: Jason A. Donenfeld <Jason@xxxxxxxxx> Jason
