The Linux kernel supplies a random number generator which is accessed
through /dev/random and /dev/urandom. Programs that utilize the random and
urandom devices, such as OpenSSH,
will benefit from these instructions.
When a Linux system starts up without much operator interaction, the entropy pool (data used to compute a random number) may be in a fairly predictable state. This creates the real possibility that the number generated at startup may always be the same. In order to counteract this effect, you should carry the entropy pool information across your shut-downs and start-ups.
Install the /etc/rc.d/init.d/random
init script included with the blfs-bootscripts-20240209 package.
