does home-manager have a way to override the global pkgs? I doesn't look like it from the docs. In that case, it looks like you'd wanna throw your overlay in nixpkgs.overlays

That doesn't quite make sense to me. So here's what you're suggesting (correct if wrong)

• add the overlay attribute to the flake.
• in the configuration attribute of the object passed to homeManagerConfiguration, I add something like this:

configuration = { config, pkgs, ... }: {
  nixpkgs.overlays = [ self.overlay ];
}

What confuses me about this is that I'm still using the pkgs argument in configuration elsewhere in the function. My intuition says that I should modify pkgs by applying the overlay to it.

I still don't understand how to add profiles/suites to a home.users.<user> in flake.nix,

In reply to @timdeh:matrix.org
so basically the way you have it now, you could just add a nixpkgs.overlays = [ self.overlay ]

The wiki lists overlay as a valid attribute of flakes; however, I'm getting this error:
