Providing a different sysvinit service name different from the systemd service name is a violation of the packaging guidelines https://wiki.debian.org/Teams/pkg-systemd/Packaging?action=show#systemd_unit_files_naming_and_installation
Wasn't this covered already in https://github.com/MariaDB/server/pull/1494 / https://jira.mariadb.org/browse/MDEV-15526 ?
