I'm trying to get something like this, but here's my situation: - I have two M1 Macs, running MacOS - I have a Ryzen desktop that dual-boots Windows 11 and NixOS 22.11 I would like to have one dotfiles repo with all my configs and home-manager setup, as well as the system / hardware config for the bare-metal NixOS installations. I have gotten these working independently, but I still can't quite make the leap in a single repo to: - Having some config be machine-specific - Having other config be OS-specific - On a particular machine (same OS - macOS), having some slightly different config, because it's a work machine vs personal (e.g. different .gitconfig setups). Can all of the above be addressed with Nix? There seems to be an assumption either you have gone all-in using NixOS (e.g. in a VM inside host OS, or bare-metal), or you are just using the package manager (+ a subset of home-manager), e.g. macOS or WSL inside Windows. But on the whole, 80% of what I want to set up and configure is machine-agnostic (NeoVIM, fish shell, basic CLI utilities, etc), and I use direnv/shell.nix in individual project folders to load the tooling for that project.
