I hadn't updated home-manager frequently in the past, but I'm realizing part of the issue is that it's the long ghc build that broke me of the habit. With an ephemeral machine my dotfiles take an hour+ before I can use it, which defeats the purpose.

I'm pulling in una the simplest way possible, at least I think. Maybe I'm making a nix mistake that's bypassing the cache somehow?

inputs = {
...
    una.url = "github:jwiegley/una";
};
...

extraSpecialArgs = { inherit una; };
...

home.packages = [
...
  una.packages.${pkgs.system}.default
...
]
