  * use caddy-frontend in `standalone style playbooks <https://lab.nexedi.com/nexedi/slapos.package/tree/master/playbook/roles/standalone-shared>`_
  * in ``templates/apache-custom-slave-list.cfg.in`` avoid repetetive ``part_list.append`` and use macro like in ERP5 SR (cf `Vincent's comment <https://lab.nexedi.com/nexedi/slapos/merge_requests/373#note_64362>`_)
