Selectively Using Service Modules from NixOS Unstable - Lemmy.World

After learning how to add an unstable overlay to nixpkgs, being able to override individual service modules from unstable was something that I still struggled with until fairly recently. Hopefully this helps someone else looking to do common-but-not-very-obvious operation.

You can import unstable as a package override

I’ve had it in the past where I can specify in the package name (like pkgs.unstable.chromium). You’ll be able to do the same with service options as most allow you to set the package they use with a config option

Yeah this is usually the way to go, I think I just got unlucky that this particular service on nixos-23.11 doesn’t have a package override option (but it will have in nixos-24.x releases!)
