Infinite Symlink recursion in path - laptop/ssd

[ghost]

During my rebuild of my configuration today I was faced with an error during the first seconds of the build. The error is unrelated to changes in my configuration (I reverse the small changes I made with git (stashed)).

The issue seems to be in the nixos-hardware/lenovo/thinkpad/x1-extreme/gen2 / gen4 module.

Error:

Removing the import of nixos-hardware fixes the problem. -> I thus conclude that the issue has to lie somewhere in the ThinkPad module of nixos-hardware.

The trace for the import is as follows:

lenovo/thinkpad/x1-extreme/gen2/default.nix: Imports the parent folder. https://github.com/NixOS/nixos-hardware/blob/4cc688ee711159b9bcb5a367be44007934e1a49d/lenovo/thinkpad/x1-extreme/gen2/default.nix#LL6C3-L8C5

lenovo/thinkpad/x1-extreme/default.nix: Imports ../../../common/pc/laptop/ssd. https://github.com/NixOS/nixos-hardware/blob/4cc688ee711159b9bcb5a367be44007934e1a49d/lenovo/thinkpad/x1-extreme/default.nix#LL5C5-L5C34

The last change in the history of the file seems to be a cosmetic/syntax change: https://github.com/NixOS/nixos-hardware/commit/03c6d1515228ff524d63f532a2a6709dfd561a70. But it was applied 6 months ago and thus seems unlikely to cause the issue.

The ssd module has no recent changes that would explain such an issue.

I thank you for your time :D
