23 is a service that restores the random seed of the
24 system at early-boot and saves it at shutdown. See

26 for details. Saving/restoring the random seed across
27 boots increases the amount of available entropy early
28 at boot. On disk the random seed is stored in
29 <code class=
"filename">/var/lib/systemd/random-seed
</code>.
