Last week I wrote about a change for the Linux kernel would better protect entropy sent in from user-space as a change driven as a result of some Linux distributions (such as Fedora) using a CPU jitter random number generator to resolve the lack of entropy at boot time and that on systemd-enabled Linux systems sometimes leading to slow boot times. That change has now ended up being queued into Linux 4.18 rather than having to wait for 4.19.
