#   e.g. run-e2e.sh debian-12 debian:12
#
# The repository is mounted read-only at /work and tests/e2e/entrypoint.sh is run
# with bash inside <image>. SU_DISTRO=<label> tells the suite which distro it is
# on. Output is shown and also written to tests/docker/logs/<label>.log.
# Exit status is the container's (i.e. the suite's) exit status.
