<title>Description</title>
<para><filename>systemd-random-seed.service</filename> is a
service that restores the random seed of the system at early boot
and saves it at shutdown. 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/systemd/random-seed</filename>.</para>
