    Is Nix good? Afaik the main selling point is that the package manager stores different software versions by hash, so all are accessible. Not sure how that works with everything else

      Isn’t it immutable? That’s a pretty big difference in itself

      edit: Thank you for the replies, I’ll have to learn more!

        it sort of is. The whole thing is made of what’s in /nix and it sets read-only attributes to all of it. You can modify it however you like by simply rebuilding it with updated configuration and you can switch at runtime or reboot.

            I’m not super adcanced in it and you beter off referring to NixOS docs to learn about it specifically, but trying to answer your question, it creates symbolic links of libs or binaries and manipulates PATH, LD_PATH and others. Some packages will also have speciall wrapper scripts that prepare the environment for a binary to run.

            The downside is that you can’t just run Linux binary directly when it’s dynamically linked and you need to use what’s in the repo or use special overlay to imitate FHS

        No, Nix isn’t actually immutable. It runs packages in isolation, but they can still affect your file system.
