# Because of the bind mounting of `configs/`, we need to run as the `root` user
# This may break in cases where user namespacing is enabled, so hopefully Docker
# sorts out a way to set permissions on bind-mounted volumes (`docker run -v`)
# before userns becomes default
# Note that not running as root will break if we don't have a matching userid
# in the container. The filesystem has also been set up to assume root.
