How do you come up with this out-of-the-box stuff?

Thanks for sharing!

I’m wondering whether it makes sense to support multiple “read” stores and only one that gets written to.

It might not be the best way to solve my problem but I’ve wanted something like this to test variations of software that shared a large common base. I’ve explored a nixos vm and virtualisation.vmVariant.virtualisation for that purpose but the result didn’t match what I expected from reading the doc (I was triggering unexpected rebuilds) and I ended up shelving the project.
