# what this does:
# if the docker user specified a UID/GID (other than 0, would be a ludicrous instruction anyways) in the image build, we will use that to create the valhalla linux user in the image. that ensures that the docker user can edit the created files on the host without sudo and with 664/775 permissions, so that users of that group can also write. the default is to give the valhalla user passwordless sudo. that also means that all commands creating files in the entrypoint script need to be executed with sudo when built with defaults..
# based on https://jtreminio.com/blog/running-docker-containers-as-current-host-user/, but this use case needed a more customized approach
# with that we can properly test if the default was used or not
