I understood it that reading from `/dev/random` will still block just after boot (i.e. before it's initialised) unless you pass the new flag `GRND_INSECURE` to `getrandom`. After it's initialised, however, it will never block because it's now just using the CRNG.

Please don't confuse `/dev/random` and `getrandom` - they are separate interfaces.
