     * The interface that allows activation scripts to restart units has been streamlined. Restarting and reloading is now done by a single file `/run/nixos/activation-restart-list` that honors `restartIfChanged` and `reloadIfChanged` of the units.
         * Preferring to reload instead of restarting can still be achieved using `/run/nixos/activation-reload-list`.
