bug: home-manager and nix-darwin error with end-of-file on nixpkgs-unstable

Are you following the right branch?

• My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

• I have searched the existing issues

Issue description

Hi, I started getting a end-of-file error while using home-manager with nix-darwin and nix flakes as of a couple of weeks ago. I've distilled it down into a minimal workable example: https://github.com/lamdor/nix-darwin-home-manager-eof-mwe Which doesn't do anything, but blows up with:

❯ nix build github:lamdor/nix-darwin-home-manager-eof-mwe#darwinConfigurations.test.system
error: unexpected end-of-file
(use '--show-trace' to show detailed location information)

Which isn't that very helpful...

When doing the --show-trace, I get

Full output

❯ nix build github:lamdor/nix-darwin-home-manager-eof-mwe#darwinConfigurations.test.system --show-trace
error: unexpected end-of-file

When I remove the home-manager.users.test = { home.stateVersion = "21.11"; }; line, basically not using any of home-manager, but still using nix-darwin, it works fine. What's odd is that I can revert my nixpkgs lock back to a commit prior to Dec 8th, and things work fine.

I've bisected nixpkgs to show that NixOS/nixpkgs#199363 was the PR that this MWE started breaking. Which is interesting since I think options-db.xml has something to do with docs and so does that PR.

Does anyone have any ideas on how to fix and what to look at next?
