http://porteus.org/
Porteus is a portable/live media Linux OS, based on Slackware and Linux Live Scripts which have been heavily modified by chief maintainer Fanthom. In essence, Porteus is a portable Slackware which started out as Fanthom keeping the Slax OS up to date as a community remix project. Unlike a standard linux install, Porteus exists in a compressed state on the portable drive. It has no /root /bin /etc file structure on the portable device itself, rather this is created on the fly during the boot process, which only takes around 20-30 seconds on a relatively new computer. It is modular in design which means extra software comes in the form of 'modules' which can be activated and injected into the live file system. It does not need to be installed and uninstalled as you may expect with other operating systems which takes numerous amounts of clicks and agreements.
