And what is the current state of /dev/urandom on Linux? Does it finally block on cold start with too little entropy? If it does, then effectively everybody can finally just use /dev/urandom, if I understand it correctly? If it's still not blocking, it seems that still the best thing to do is using getrandom( ..., 0 )?
