That doesn't seem like a critical issue, just adjust the paths in my example to match whatever you need.
I think it is, unless
/dev
in the container is a bind-mount with shared propagation, how can I make/dev/nvidia
appear inside the container without a subdirectory?
# mkdir /tmp/scratch
# podman run -it --rm --volume /tmp/scratch/:/tmp/scratch:shared docker.io/library/busybox
/ # ls -l /dev/
