58                 is a service that restores the random seed of the
59                 system at early-boot and saves it at shutdown. See
60                 <citerefentry><refentrytitle>random</refentrytitle><manvolnum>4</manvolnum></citerefentry>
61                 for details. Saving/restoring the random seed across
62                 boots increases the amount of available entropy early
63                 at boot. On disk the random seed is stored in
64                 <filename>/var/lib/systemd/random-seed</filename>.</para>
