I appreciate someone from the project commenting here. I left Nix because it just has too many warts, and unfortunately, they've only increased over time, which is the opposite of what I expected.
- I'd update Nixpkgs, and my build would stop working. The logging was awful, so fixing it took hours.
- The mono repo sounds nice, but selective updates are almost impossible.
- Building our Go project in a Nix package was nearly impossible with private GitHub repos, so we moved on.
- Bash scripts never work because binaries are never where they should be in Linux.
I could go on, but my experience with Nix and NixOS left me with significant scars. I’m hopeful that someone will eventually create a more user-friendly deterministic OS.
