title: Debian squeeze and setting ulimit
body: <p>All</p>
  
  <p>I want to permanently set the core file size to unlimited.
  Reading about it, the suggestion is to modify the /etc/security/limits.conf. 
  I have done so with the following line:</p>
  
  <ul>
  <li>soft    core            10000
  root            hard    core            10000</li>
  </ul>
  
  <p>I reboot after the change and I issue ulimit -a and core is still set to 0.
  Can not understand why the setting is not working. What can be overwriting it? </p>
