+                is an early-boot service that restores the random seed
+                of the
+                system. <filename>systemd-random-seed-save.service</filename>
+                is a late-shutdown service that saves the random seed
+                of the system. See
+                <citerefentry><refentrytitle>random</refentrytitle><manvolnum>4</manvolnum></citerefentry>
+                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
+                <filename>/var/lib/random-seed</filename>.</para>
