NAME

       systemd-random-seed.service, systemd-random-seed - Load and save the system random seed at boot and shutdown

SYNOPSIS

       systemd-random-seed.service

       /usr/lib/systemd/systemd-random-seed

DESCRIPTION

       systemd-random-seed.service is a service that restores the random seed of the system at early-boot and saves it at shutdown. See random(4)
       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 /var/lib/systemd/random-seed.

SEE ALSO

       systemd(1), random(4)

SYSTEMD-CRYPTSETUP@.SERVICE(8)				    systemd-cryptsetup@.service 			    SYSTEMD-CRYPTSETUP@.SERVICE(8)

NAME

       systemd-cryptsetup@.service, systemd-cryptsetup - Full disk decryption logic

SYNOPSIS

       systemd-cryptsetup@.service

       /usr/lib/systemd/systemd-cryptsetup

DESCRIPTION

       systemd-cryptsetup@.service is a service responsible for setting up encrypted block devices. It is instantiated for each device that
       requires decryption for access.

       systemd-cryptsetup@.service will ask for hard disk passwords via the password agent logic[1], in order to query the user for the password
       using the right mechanism at boot and during runtime.

       At early boot and when the system manager configuration is reloaded this /etc/crypttab is translated into systemd-cryptsetup@.service units
       by systemd-cryptsetup-generator(8).
