## 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`.
