- 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.
I believe they had to end up changing the design in their 2nd iteration...
Yes. This is a nightmare, and is the literal step-one problem FlakeHub is designed to solve.
Regarding the monorepo causing big-bang updates that broke all your stuff: continued, strong, agreement. I think as nixpkgs continues to grow, and usage grows, we'll see a wider adoption of flakes from a pure "how do we all work together?" perspective. That's the flip side of FlakeHub's initial concept.
