Build a Linux 4 Tegra with CUDA Ubuntu 22.04 docker image for the nVidia Jetson Nano using its final JetPak 4.6.3

Dockerfile

# Make an Ubuntu 22.04 Docker image supporting CUDA and Linux 4 Tegra stuff on
# the nVidia Jetson Nano.  I ran this from the final nano Linux 4 Tegra JetPak
# image aka jetson-nano-jp461-sd-card-image.zip which I updated to 4.6.3
# using apt.  -- @gpshead
#
# Is there any real point to doing this?  I have no idea. :P
# If you don't care about toying with the GPU stuff, just go install Armbian.
#
# This is based off of the instructions on
# https://github.com/NVIDIA/nvidia-docker/wiki/NVIDIA-Container-Runtime-on-Jetson
# and the final Jetpak 32.x container that represents the final Jetson Nano
# platform from https://catalog.ngc.nvidia.com/orgs/nvidia/containers/l4t-base
# before nvidia went ass-hole and abandoned three generations of hardware that
# they still ship.

Realistically this image is huge and contains all of the jetpak gui desktop software mega-bloat that nobody ever wants. If you have a specific use for this, at least make some of the first steps minimize the image before any upgrades.

Starting to run through this - if anyone else is following this, on installed clean image of jetpack 4.6.3, after running sudo apt update && sudo apt upgrade -y, the command sudo apt install nvidia-jetpack is likely to fail. The fix for that is:

sudo apt dist-upgrade
sudo apt update
sudo apt-get install nvidia-container
sudo apt-get install nvidia-jetpack
