<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>
