Code Example

Show what the library does as concisely as possible, developers should be able to figure out how your project solves their problem by looking at the code example. Make sure the API you are showing off is obvious, and that your code is short and concise.

Ubuntu Auto Install

This allows user to do automated installation of ubuntu. Provided here a a few different files/scripts for making this easier.

I've used this to verify that d-i kernel and initramfs from -proposed work as shown in bug 1511497.
