I just switched one of my systems over to NixOS from Arch and so far it seems interesting. One question I had is regarding the nix-shell. So I get the basic concept of it and that it allows creating a shell that has packages installed with that shell making ideal for dev environments. I’ve even seen talks where the suggest nix-shells over docker/podman, my question is how is persistent data (like databases) handled?
Honestly, I barely use it at all these days. I do most of my computing from my phone, so would be very hesitant to just blow that away on a whim like that. But on the desktop where I don’t do much, it’s fine.
