# ermite-runner-ubuntu-26.04: the minimal CI-1 runner image. The same
# filesystem is used as an OCI image (container isolation) and exported to an
# ext4 base image (vm isolation) by scripts/build-image.sh. It holds the OS
# only: the runner executable is attached by the host at start (never baked
# in), so a runner upgrade does not need an image rebuild.
