"I use NixOS btw..." Learnings from 2 years daily driving NixOS
summary
Daily-driving NixOS for two years produces concrete lessons: Nix is a language + package manager + OS that guarantees reproducible builds by pinning commits and content hashes, but it’s fragile in practice with poor docs and hairy error messages. Nixpkgs is huge (tens of thousands of derivations; cloning can take hours), the Nix store intentionally accumulates many per-package variants (e.g. multiple Python 3.x installs) to isolate deps, and tools like devbox (definition + lock file) make developer onboarding and CI parity practical yet adoption remains challenging.
