 # fake_nvidia: an NVIDIA PC for the nvidia suite. A fake RTX 5080 in a fake DRM tree (NVIDIA_DRM_DIR is Steamify's test hook, exported
 # here: call it in every guest command that runs the wizard) and fake NVIDIA modules for every installed kernel (renamed copies of a
 # tiny module, then depmod), so `modinfo nvidia_drm` finds one and the initramfs build has modules to put in.
