title: MySQL 5.6.10 installation error
body: <p>I am getting this error while installing MySQL 5.6.10. I have other versions of MySQL (5.1 and 4.1) installed and there seems to be a conflict in the my.cnf.</p>
  
  <p>Removing <code>/etc/my.cnf</code> is not an option. </p>
  
  <pre><code>[amitra@dev4.lab user.amitra]$ sudo /usr/local/mysql5610/scripts/mysql_install_db --basedir=/usr/local/mysql5610/ --datadir=/var/home/amitra/mysql5610/user.amitra

  <p>I also tried to install using <code>--defaults-file=/usr/local/mysql5610/my.cnf</code> but that didn't work.</p>
