+ systems, auto is equivalent to <opt>journal</opt>, in case <opt>daemonize</opt>
+ is enabled, and to <opt>stderr</opt> otherwise. If set to <opt>file:PATH</opt>,
+ logging is directed to the file indicated by PATH. <opt>newfile:PATH</opt> is
+ otherwise the same as <opt>file:PATH</opt>, but existing files are never
+ overwritten. If the specified file already exists, a suffix is added to
+ the file name to avoid overwriting. Defaults to <opt>auto</opt>. The
