# "ubuntu" is the default user on ubuntu images with UID=1000. This user is used for two reasons:
#   1. It's generally a good practice to run containers as non-root users. See https://www.docker.com/blog/understanding-the-docker-user-instruction/
#   2. Docker Spaces on HuggingFace don't support running containers as root. See https://huggingface.co./docs/hub/en/spaces-sdks-docker#permissions
