title: Which parts of the apache sites-available file are necessary?
body: <p>I noticed that the default sites-available file (/etc/apache2/sites-available/default) contained many "directory" tags with various options.</p>
  
  <p><code>&lt;Directory /&gt;</code>, <code>&lt;Directory /var/www/&gt;</code>, <code>&lt;Directory "/usr/lib/cgi-bin"&gt;</code>, and <code>&lt;Directory "/usr/share/doc/"&gt;</code></p>
  
  <p>Do I need any of those, or can I safely remove them?</p>
