This is meant to distinguish OCI containers and images that are designed
specifically for Toolbx from others. Toolbx containers are long-lasting
pet containers for interactive command line use, which makes them
substantially different from short-lived containers running services.
Therefore, it can be useful to be able to identify Toolbx containers and
images when generating statistics about Fedora usage.
