master images of an OS are created, and thus replicated into every
installation. If OS image builders carefully reset the random seed file
before generating the image it should be safe to credit entropy, which can
be enabled by setting the `$SYSTEMD_RANDOM_SEED` environment variable for
the service to `1`. Note however, that this service typically runs
relatively late during early boot: long after the initial RAM disk
(`initrd`) completed, and after the `/var/` file system became
writable. This is usually too late for many applications, it is hence not
advised to rely exclusively on this functionality to seed the kernel's

entropy pool. Also note that this service synchronously waits until the
kernel's entropy pool is initialized before completing start-up. It may thus
be used by other services as synchronization point to order against, if they
