It seems one of the mariadb updates somehow disabled its service file. I
noticed this after a server reboot - mariadb wasn't started anymore.

# systemctl status mysql.service 
mysql.service - MySQL server
   Loaded: loaded (/usr/lib/systemd/system/mysql.service; disabled)
                                                          ^^^^^^^^

Now the question is when and how this happened. I didn't reboot that server for
quite a while, but I'm sure mariadb was enabled and automatically started at
previous reboots.
