|
|
<para><filename>systemd-random-seed-load.service</filename>
|
|
is an early-boot service that restores the random seed
|
|
of the
|
|
system. <filename>systemd-random-seed-save.service</filename>
|
|
is a late-shutdown service that saves the random seed
|
|
of the system. 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/random-seed</filename>.</para>
