DESCRIPTION
       systemd-random-seed.service is a service that restores the random seed of the system at early-boot and saves it at shutdown. See random(4)
       for details. Saving/restoring the random seed across boots increases the amount of available entropy early at boot. On disk the random seed
       is stored in /var/lib/systemd/random-seed.
