1.106 deraadt 102: A small bug in the installation script causes the <code>/etc/hosts</code> file to
103: be incorrectly formed.<br>
104: The resulting file contains a line which reads like:<p>
105: <code> #.#.#.# hostname. hostname</code>

108: <code> #.#.#.# hostname.domainname.com hostname</code>
