Hi! Like most nix users (I think), I use github as the authoritative source for package definitions.
However, github seems to have become more and more unreliable lately, and I can’t afford to waste time whenever they happen to be down.
So my questions about this are:
- Are there any official mirrors?
- I found this mirror which apparently seems to be automated: https://gitlab.com/xaverdh/nixpkgs . How do I tell e.g. fetchTarball to use it as a fallback to github? Maybe some kind of impure env var like this? https://github.com/NixOS/nixpkgs/commit/76a8d120a41c2631688f42cc2cab0b225210bc8e I can’t seem to find any documentation around this.
