Isso ilustra uma instância rara na qual installf é apropriada em um script de ação de classe. Pelo fato do arquivo space ser usado para reservar espaço em um sistema de arquivos específico, este novo arquivo pode ser adicionado seguramente, mesmo se não estiver incluído no arquivo pkgmap.
O script de remoção r.cfgdata

# the configuration data is so valuable that it should be
# backed up to $PKGSAV before it is removed!
