Super interesting. I can clearly see how this improves the caching story compared to vanilla Kubernetes+containerd, and therefore the potential this has to improve autoscaling performance.
Of course, it understandably requires the host VM to be NixOS, which means my Kubernetes cluster needs to be running NixOS, which means I would need to abandon the ease afforded by EKS/GKE... which is a tall ask. It would be great if there was a way to more easily add this into popular managed Kubernetes distributions, to play around more with running "Nix images", simply by adding nodeSelector and/or node affinity to the Kubernetes manifests.
