Loading configs from different file systems

How to load configs from OS file system and built-in file system at the same time?

Afair it was done in https://github.com/cristalhq/aconfig/pull/126/files but not well documented. PRs are welcome.

As far as I understand, we can use either the embed file system or the OS. But is it possible to use both at the same time? For example, I want to embed a configuration file into the binary, and when the application starts, read the configuration from both the embed and the OS file system

Well, theoretically you can create a loader for fs or OS but that's a hack. Better would be add FileSys fs.FS field to Config and make it work.

However, mixing fs and real OS under one field sounds hacky again. should it be FileSys []fs.FS ? no idea tbh. Do you have something on your mind?

not yet, thinking about it. what comes to mind breaks the LoaderFor function. it could accept several configs and merge them. but for now this idea doesn't seem optimal

this idea has a place to be because for different file systems there can be different configs and different loaders. however, they have common parameters, for example, SkipFlags and others. it is not good that they will be duplicated in different configs
