systemd-random-seed-load.service
is an early-boot service that restores the random seed
of the
system. systemd-random-seed-save.service
is a late-shutdown service that saves the random seed
of the system. See

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.
