FaunOS is based on Arch Linux and is one of a growing number of distributions available for use on a USB flash drive (minimum 1GB). It comes the KDE desktop environment and a full complement of useful applications, including The Firefox Internet browser, OpenOffice.org word processing suite, Audacity audio editor and recorder, and the Google Earth mapping tool. One feature that makes FaunOS stand out is its ability to save system changes at shutdown. Although you'll need to be mindful that the drive to which you're saving has enough free space to accommodate the new or changed data, it's possible to resize the system partition using a good partition manager.
