I can't find anything on this so far from google.

There's also a second problem I'm having, I want to include a private module in my doom configuration, however it appears that if I include it as a git submodule, it hangs. What do others do when they want to publish both a module and their doom config? Is there an alternative to git-submodule which can be used for that purpose?

Ah, I had forgotten to push the commit that disabled cloning submodules, that is up there now if anyone else happens to want to evaluate it, although I expect noone does.

Oh, this is weird. I guess it's about the whole thing where i'm in a flake but not using it as a flake input? It's looking for the flake.lock in my source and that exists, but it doesn't have any of the stuff it's looking for? Or does it get downloaded somewhere else with its own flake.lock when I fetch it with fetchTarball?

Unfortunately this is really giving me trouble. I'm thinking I will have to just install emacs normally and do my config without using home manager and nix-doom-emacs for now.

I'm have been getting this error on nixos-rebuild switch --upgrade for the past couple of days.
Anyone else run into this?
