How to install a previous version of a specific package with configuration.nix?

I’d argue that fetching a particular version of nixpkgs within a package recipe isn’t a very tidy/elegant thing to do. (In kinda the same sense that it’s nicer to have a package definition that builds from source compared to one that runs a prebuilt binary).

Agreed – my solution is a hack, but sometimes you just need a hack to test something out LOL. The right solution is to build from source as you recomment
