Guix has reproducibility. Instead of Nonguix, which bundles tons of propietary software, they can just add the Fearware repo, which just has the tainted non-free vanilla Linux kernel with closed blobs and firmware, just enough to function your machine well (especially with 3D support for Radeon cards and wireless devices) and nothing more.

Do you have a link to this ‘Fearware’ channel? I’ve only heard of nonguix.
