  32
  33     <para><filename>systemd-random-seed.service</filename> is a
  34     service that restores the random seed of the system at early boot
  35     and saves it at shutdown. See
  36     <citerefentry><refentrytitle>random</refentrytitle><manvolnum>4</manvolnum></citerefentry>
  37     for details. Saving/restoring the random seed across boots
  38     increases the amount of available entropy early at boot. On disk
  39     the random seed is stored in
  40     <filename>/var/lib/systemd/random-seed</filename>.</para>
