You’re probably right. The mysqld service is an hack. Back to ns7 early days I produced this ugly workaround to make our mysqld configuration backward-compatible:
# cat /usr/lib/systemd/system/mysqld.service
.include mariadb.service
I heard systemd has some kind of unit name “aliasing”. If true, configuring it would be the issue #1 solution.
Added a project card here.
