# This script is a wrapper creating the same user inside container as the one
# running the docker/build.sh outside the container. It also set the home directory
# for the user inside container to match the same absolute path as the workspace
# outside of container.  Do not run this manually. It does not make sense. It is
# intended to be called by ci_build.sh only.
