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