From: "Bedel, Alban" <[email protected]> It do make sense to start rngd early in the boot process because otherwise we would need to track every service that might need entropy and explicitly configure it to start after rngd.
When used with systemd rngd blocked the shutdown process because it simply missed the proper unit configuration. As the systemd documentation explains, when using DefaultDependencies=no one also have to explicitly configure the unit to properly stop at some point. This is normaly achieved by having Before=shutdown.target and Conflicts=shutdown.target set for the unit. To have rngd started early again we reverte the changes done to rngd.service in commit edf7606822 (rng-tools: fix rngd blocks system shutdown). To have it properly stopped on shutdown we also add Before=shutdown.target and Conflicts=shutdown.target.
