# Ab dem Zeitpunkt in dem Python auf dem Zielsystem vorhanden ist,
# kann Ansible wieder normale Module (wie apt, file, service, copy, usw.) benutzen.
# 
# Aber:
# Da gather_facts: false gesetzt war, hat Ansible bis hierher keine Systeminformationen (Facts) wie:
# 
#     ansible_distribution
# 
#     ansible_fqdn
# 
#     ansible_memtotal_mb
# 
#     ansible_interfaces
# 
#     etc.
#     eingesammelt.
# 
# Rufe das 'setup'-Modul manuell auf mit:
#
#    - name: Enable facts now that Python exists
#       ansible.builtin.setup:
# 
# Damit holt Ansible nachträglich die Facts, jetzt, wo Python verfügbar ist.
