    -v /tmp/sockets:/tmp/sockets:rw \
    -e HOST_APPS_STATE_FOLDER=/etc/wolf \
    -v /etc/wolf:/etc/wolf:rw \
    -v /var/run/docker.sock:/var/run/docker.sock:rw \
    --gpus=all \
    --device /dev/dri \
    --device /dev/uinput \
    --device /dev/uhid \
    -v /dev/:/dev/:rw \

With this PR Wolf is able to automatically run the container toolkit with the right flags when the drivers are missing , unfortunately for this to work properly we are still missing libnvidia-vulkan-producer.so which will be provided once NVIDIA/nvidia-container-toolkit#548 will get merged.

Wolf + Sway seems to already successfully run, it's just Gamescope that doesn't work since it requires Vulkan.
