I love NixOS, and the nvidia-x11 package is truly wonderful and captures so many options. But having such a complex package makes updating and regression testing take time. For ML stuff I ended up using it as the basis for an overlay, and ripping out literally everything I don’t need, which makes it a matter of minutes usually to make the changes requires to upgrade when a new driver is released I’m running completely headless because these are H100 nodes, and I just need persistenced and fabricmanager, and GDRMA (which wasn’t working at all, causing me to go down this rabbit hole of stripping everything away until I could figure out why).

I was going to say specialisations might be useful for you to keep a previous driver version around for testing but you might be past that point!

Having the ability to keep alternate configurations for $previous_kernel and $nvidia_stable have been super helpful in diagnosing instead of rolling back.
