title: MariaDB default my.cnf in sources
body: <p>Does MariaDB have a default my.cnf in their sources that contains all params and their default values? I found only <a href="https://github.com/MariaDB/server/blob/10.3/debian/additions/my.cnf" rel="nofollow noreferrer"><code>debian/additions/my.cnf</code></a> but it does not reflect all params and seems to be updated occasionally. </p>
  
  <p>For example, PHP has default <a href="https://github.com/php/php-src/blob/master/php.ini-development" rel="nofollow noreferrer"><code>php.ini</code></a> in their sources, so when they change a default value or add a new option they update this file. While upgrading PHP I compare hash sums of original configs and see if something has been changed. I wonder whether MariaDB has a similar file. </p>
