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/random-seed.
