Alternatively, the "feel free to leak all my data but please use my GPUs and don't rm -rf /" config:

  {
    "sandbox": {
      "enabled": true,
      "filesystem": {
        "allowRead": ["/"],
        "allowWrite": [
          ".",
          "/tmp",
          "/dev/nvidia0",
          "/dev/nvidia1",
          "/dev/nvidia2",
          "/dev/nvidia3",
          "/dev/nvidia4",
          "/dev/nvidia5",
          "/dev/nvidia6",
          "/dev/nvidia7",
          "/dev/nvidia8",
          "/dev/nvidiactl",
          "/dev/nvidia-uvm"
        ]
      }
    }
  }
