Attempting to clone your config and have met with errors. Requesting any insight you can spare

[pyunramura]

Hey, I'm currently attempting to clone your config, specifically your "io" host. And while I was able to build the flake into a vm with nixos-rebuild build-vm github:fufexan/dotfiles#io and boot it up successfully I'm unfortunately getting errors while attempting to deploy it onto baremetal. I'm fairly new to NixOS flakes and while I do have a working flake deployment I'm not really happy with it and am in the process of blowing it away in lieu of the one you have configured as it's fantastic. I've forked your config already and just made a few small alterations such as changing the username, and disabling howdy and the ir-emitter since I'm deploying onto an AMD desktop and don't have any method of biometric authentication. I was hoping you might have some insight into the errors that I'm seeing, and I sincerely appreciate any insight you have.

I can provide you some error logs if you'd like but I'm not sure if I should drop them here or a pastebin service, etc. Just let me know if you'd be willing. Thanks for the consideration.

@pyunramura have you changed the hosts/io/hardware-configuration.nix file? It is specific to my disk layout, so unless you have the same layout, it will not work. I suggest running nixos-generate-config and copying that file from /etc/nixos into the hosts/io directory of the cloned repo.

[pyunramura]

Oh sorry I didn't think to mention it before but I adjusted my disk configuration to match what you have configured prior to the build attempt. I just created two partitions labeled EFI and NixOS respectively on a spare ssd to test the build process. I have looked through your hardware-configuration.nix though and it matches my current configuration aside from the partition label capitalization.

I'll go ahead and post the error log here to give more info on the nature of the problem. If you'd prefer a pastebin link or otherwise I'd be happy to oblige.

I'm just not certain what in the config is being built while calling that nix store path, as it seems to be failing by not being able to find the Cargo.toml.

Looks like nh is the issue here. Try updating the lockfile. Or using the commit I have in mine, as it works currently.

I attempted to update the lock file but it didn't seem to make a difference. I did however manage to get it deployed though by disabling nh in the config. Oddly enough once booted into the new installation I successfully rebuilt with nh enabled. The odd behavior probably points to an issue with my current deployment, though it also displayed the same behavior for me when attempting to deploy the flake from the NixOS installation media. Not really sure where the problem lies, but I haven't tried replicating the results yet. Anyway, thank you very much for the nh tip, it made all the difference. I'll consider the issue closed. Thanks again for your help.

[pyunramura]

Just an additional point of reference to the problem I was seeing with viperML/nh. It seems there's a problem using nixos-install with nh as reported by this issue. Good thing to keep in mind if you're going to be doing a clean install in the future, just disable nh for the installation.
