edcf89be | 56 | |
798d3a52 | 57 | <para><filename>systemd-random-seed.service</filename> is a |
b938cb90 | 58 | service that restores the random seed of the system at early boot |
798d3a52 ZJS |
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> | |
