> This is not actionable and has been discussed before

I don't know if #19830 should count as a discussion, considering the author was speaking through a translator and was clearly upset by some brush with the Void Linux community...

> `void-packages` is by design a monorepo which comes with its advantages and limitations, hacking around them is not supported.

Sure, but it's still useful to have some semblance of user repositories, especially when you think of all the juicy new contributors that could come from these user repositories. I thought we might discuss some hacks for user repositories, even if they aren't "officially" supported.

For instance, after much contemplation, I came up with [this](https://github.com/freddylist/xbps-src-overlay-demo), which (ab)uses `overlayfs` to trick `xbps-src` into finding templates from multiple directories.

It was mentioned in the other issue that supporting multiple `srcpkgs` dirs was "[the wrong way of handling the issue](https://github.com/void-linux/void-packages/issues/19830#issuecomment-595679246)" and that it would be "[hard to implement a way how to supply multiple directories](https://github.com/void-linux/void-packages/issues/19830#issuecomment-595695312)", but not *why*. Maybe there is a lot about package management I don't understand, but I don't see how it could be a bad idea to support multiple `srcpkgs` dirs. Just skimming through the `xbps-src` code I think it might be a couple dozen extra lines of Bash to implement multiple `srcpkgs` dirs in a non-breaking way.

Unless I am convinced otherwise or have grossly underestimated how hard it would be to implement, I can maybe have a draft version of `xbps-src` that supports multiple `srcpkgs` dirs, probably configured the same way my hack above is (symlinks in some `repos/` directory or something).
