# The "ansible" directive is non-functional in Debian 12 Bookworm.
#
# Since Ansible in Debian Bookworm is version 2.14, UTF8 is mandatory :
# https://docs.ansible.com/ansible/devel/porting_guides/porting_guide_7.html#command-line
#
# This is taken into account in vmdb2 0.27, see 5th bullet point in 0.27 section, here :
# http://git.liw.fi/vmdb2/tree/NEWS
#
# Unfortunately, Bookworm uses vmdb2 0.26, which has UTF8 missing when calling vmdb2.
# To fix that in Bookworm, we call the ansible-playbook command directly.

# This directive is commented for now (Bookworm)
#  - ansible: root
#    playbook: vmdb2-ansible.yaml
# Will be uncommented when Debian 13 Trixie becomes stable

# This directive bloc should be removed when Debian 13 Trixie becomes stable
