        MariaDB and MySQL cannot be installed on the same system without 
        extensive changes to the build configuration of one of the two applications.
      </para>

    <para>
      For security reasons, running the server as an unprivileged user
      and group is strongly encouraged. Issue the following (as

      user and group:
