title: Can I safely delete all content in /var/lib/php5?
body: <p>I have over 5 million session files in <code>/var/lib/php5</code>
  I would like to delete all files in this folder using <code>rm *</code>, however I'm not sure if there are other files other than the session files in that directory that should not be deleted.</p>
  
  <p>Through SSH it took a few minutes to make the file count and I'm not sure I can navigate through there with all these random filenames.
  The setup is ubuntu lucid linx, apache 2 and php5. In the most common of setups are there other folders / files in <code>/var/lib/php5</code> that I should not delete?</p>
  
  <p><strong>Edit</strong> The reason I want to remove the files is because I moved session handling to a database and don't need any of the files anymore.</p>
