</div>None of them do, because Sugar can be used on hardware which does not<br>
provide a serial number, and more than one instance of Sugar can be<br>
used on devices that do provide a serial number. You must find<br>
another way to ensure uniqueness, such as registration to a central<br>
authority database.<br>
<br>
The aboutcomputer control panel section contains legacy code specific<br>
to the OLPC XO laptop. You should not design on that basis alone.<br>
