Discussion:
The service will ask docker to mount the binary which is not provided by the Nvidia driver v470. Using NixOS 24.05 with nixpkgs . Steps to reproduce the behavior: should not be mounted when the binary is missing. <img width="1234" alt="image" src=""<img width="854" alt="image" src="" Edited: a workaround Add a :+1: [reaction] to [issues you find important].

Thank you for the report You can also set in the meantime. I'll open a PR as soon as possible.
