>
> Currently, access to `/dev/nvidiactl` and `/dev/nvidia-uvm` is only granted
> to / revoked from a container as GPUs are added and removed from them. On
> some level, this makes sense because most jobs don't need access to these
> devices unless they are also using a GPU. However, there are cases when
> access to these files is appropriate, even when not making use of a GPU.
> Running `nvidia-smi` to control the global state of the underlying nvidia
> driver, for example.
>
> We should add `/dev/nvidiactl` and `/dev/nvidia-uvm` to the default whitelist
> of devices to include in every container when the `gpu/nvidia` isolator is
> enabled. This will allow a container to run standard nvidia driver tools
> (such as `nvidia-smi`) without failing with abnormal errors when no GPUs have
> been granted to it. As such, these tools will now report that no GPUs are
> installed instead of failing abnormally.
