classroom-webapp.service on workstation fails every time and systemd is restarting it and it uses podman to create a jupyter service and tries to connect to /run/media/meta-data/openstack/latest, which does not exist, and basically fills the root filesystem with images in /var/tmp/storage[[:digit:]]* directories.

After a while students can't do anything and sometimes if they are unlucky and they logged out of the workstation, can't even log back in.
