Can Unbound save cached DNS record to file on shutdown and then, read file of cached records on startup?I know that unbound-control can load and dump the cache.But can Unbound finish this two operations itself automatically？

       dump_cache: The contents of the cache is printed in a text format to stdout.
              You can redirect it to a file to store the cache in a file.

       load_cache:
              The contents of the cache is loaded from stdin.  Uses  the  same
              format as dump_cache uses.
