For real though, containerization isn't the only way to separate applications from each other but totally fine, it's the "It works on my machine, so here's my machine" mentality that doesn't fill me with confidence. I've seen too much barely-working jank in containers that probably only get updated when a new version of the containerized application itself is released.

How do you separate Nix programs from the rest of the system?

It creates a set of symlinks so every program sees exactly the dependencies it needs.

You can also create a container:

Or you can create reproducible docker containers with nix:

The secret sauce with nix is reproducibility. If it builds once, it will continue building exactly like that forever. Bit by bit.

That's very interesting, I was aware of how NixOS separated dependency versions but I didn't know it natively supported containers.
