How to use patches in a channel flake input in develop?

[andrevmatos]

I'm using current develop branch, and I'm trying to apply some patches from upstream's open PRs to my current nixos system. Trying to add patches array directly to channels.nixos in flake.nix gives me the following error:

error: The option `channels.nixos.patches' does not exist. Definition values:
       - In `<unknown-file>':
           [
             /nix/store/lflzsw176h3p295fy7jp7zmxbss9fjnq-source/pkgs/127389.patch
           ]
(use '--show-trace' to show detailed location information)

So it seems despite fup accepting the patches input, some module type declaration doesn't like it. How can I use fup's channel patches functionality on current devos?

It'd be interesting to have some documentation on it, specially if there's a way to automatically fetch these patches remotely directly on flake.nix body or flake = false inputs.

Yeah to use patches we have to add the option to the channel submodule. We're sort of holding out for NixOS/nix#3920 as that would be the optimal solution. But I would be ok to review a PR to add the option to digga(can't say the same for others) as a temporary solution. Its just not something I plan to do myself, since I don't have much need for patches.

in addition, fup's patches only work for nixpkgs.
