Sorry for the verbose title but as title says:
Setting nixpkgs.overlays in Home Manager Module on NixOS or nix-darwin cause warning on when home-manager.useGlobalPkgs = true. I've encountered this warning when switching my NixOS config:
evaluation warning: <user> profile: You have set either `nixpkgs.config` or `nixpkgs.overlays` while using `home-manager.useGlobalPkgs`.
This will soon not be possible. Please remove all `nixpkgs` options when using `home-manager.useGlobalPkgs`.
I have no nixpkgs.config nor nixpkgs.overlay config on my home manager files. So I started looking at how I set up my home manager modules and found out that I had a redundant use of NUR modules because I have on NixOS and Home Manager at the same time, and also configured the overlay on nixpkgs.
It's not easy to know where how this happens. So I would advise a warning on the README or some assertion in the module which I don't how feasible is to do.
TL;DR: But either way, I want to create this issue in case someone else bumps into this themselves. Just setup the overlay manually and do not import hm module.
