+#   [mysqld]
+#   basedir=<path-to-mysql-installation-directory>
+# - Add the above to any other configuration file (for example ~/.my.ini)
+#   and copy my_print_defaults to /usr/bin
+# - Add the path to the mysql-installation-directory to the basedir variable
+#   below.
+#
+# If you want to affect other MariaDB variables, you should make your changes
+# in the /etc/my.cnf, ~/.my.cnf or other MariaDB configuration files.
