RootStock 0.1.99.4 Description:
RootStock's goal is to create a command-line and graphical set of tools to make a fully configured tarball or VM image of an Ubuntu rootfs from scratch so that you can extract it to a root device on e.g. armel systems. Creating a rootfs can help you testing Ubuntu in devices that are not official supported. It also helps you if you want to create smaller images, or just different flavors of Ubuntu (with Gnome, KDE, XFCE, etc).
