  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>
