getrandom waits for a long time when /dev/random is insufficiently read from
...the urandom pool has been replaced by an actual CSPRNG using the ChaCha-20 stream cipher. The getrandom(2) system call uses the same output pool (4.7 and earlier) or CSPRG (starting with v4.8-rc1) as /dev/urandom. The big difference is that it blocks until we know for sure that the output pool or CSRPNG has been seeded with 128 bits of entropy. We don't do this with /dev/urandom for backwards compatibility reasons. (For example, if we did make /dev/urandom block until it was seeded, it would break systemd, because systemd and progams run by systemd draws from /dev/urandom before it has been...
