It is legal to use "configfile <top level filename>" where filename does
not contain directory part. In this case config_directory is set to filename.
Set it to empty string so $config_directory/file works as expected.
May be it makes sense to generate full pathname (including device part)
so that interpretation of $config_directory does not depend on possible
change of $root.
