58 | is a service that restores the random seed of the | |
59 | system at early-boot and saves it at shutdown. See | |
edcf89be LP |
60 | <citerefentry><refentrytitle>random</refentrytitle><manvolnum>4</manvolnum></citerefentry> |
61 | for details. Saving/restoring the random seed across | |
62 | boots increases the amount of available entropy early | |
63 | at boot. On disk the random seed is stored in | |
64 | <filename>/var/lib/random-seed</filename>.</para> | |
