How to write back config load via viper.Unmarshal(&config)?

[hyorigo]

Usually, we change the value with viper.Set() and then viper.WriteConfig() to write back.

What about the config load via viper.Unmarshal(&config)? How to set the config and write back?

It's not currently possible at the moment and I doubt this will ever be a feature. WriteConfig is not supposed to be used as a means to save the configuration changes, rather to dump a state so you can create eg. a default config file.
