FAI’s default utilities were not useful enough for me, so I went and converted them to Ruby in order to modify them as needed.

For many parts, feature sets of the scripts are smaller than original scripts’, though there is some subtle changes and one feature addition: ability to use own custom initrd in a FAI CD. There is also separate base archive creation script.
