e735f4d4 | 32 | <para><filename>systemd-random-seed.service</filename> is a |
db2df898 | 33 | service that restores the random seed of the system at early boot |
e735f4d4 MP |
34 | and saves it at shutdown. See |
35 | <citerefentry><refentrytitle>random</refentrytitle><manvolnum>4</manvolnum></citerefentry> | |
36 | for details. Saving/restoring the random seed across boots | |
37 | increases the amount of available entropy early at boot. On disk | |
38 | the random seed is stored in | |
39 | <filename>/var/lib/systemd/random-seed</filename>.</para> | |
