# MariaDB owns its own data directory. The container runs as uid 999 and has to
# create files in there; this playbook declared owner: {{ ansible_user }} (1000),
# which had been drifting from reality ever since the containers were created and
# would have broken MariaDB the first time it needed a new file. It went
# unnoticed only because the playbook had not been run since.
#
# So: ensure the directory exists, and let the container own it. On a fresh
# install the mariadb image's entrypoint sets ownership itself.
