I didn't notice in past, but this should become:

appConfig := defaultConfig // copy default config so it's not overwritten
config, err := yaml.NewConfigWithFile(path, ucfg.PathSep("."))
if err != nil {
    fmt.Fprintln(err)
    os.Exit(1)
}
err = config.Unpack(&appConfig)
if err != nil {
    fmt.Fprintln(err)
    os.Exit(1)
}
