Ubuntu Privacy Remix is a modified live CD based on Ubuntu Linux. UPR is not intended for permanent installation on a hard disk. The goal of Ubuntu Privacy Remix is to provide an isolated working environment where private data can be dealt with safely. The system installed on the computer running UPR remains untouched. It does this by removing support for network devices as well as local hard disks. Ubuntu Privacy Remix includes TrueCrypt and GnuPG for encryption and introduces "extended TrueCrypt volumes".
Toorox is a Linux live DVD based on Gentoo which starts as bootable media using KNOPPIX technology. It is designed for ease of use, with a simple control center and a hard disk installer.

It is multi-lingual and contains the unstable branch of Gentoo (x86 and amd64).
TurnKey PostgreSQL Appliance is a server appliance for PostgreSQL, a fully-featured object-relational database with many enterprise features: ACID transactions, inheritance, Unicode, and strong support for the SQL-92 standard including subqueries, views, outer joins, foreign keys, sequences, and triggers. It is designed to be easy to use and easy to maintain. Security patches are automatically installed. It provides a Web management interface, configuration console, and an AJAX Web shell. To minimize footprint the appliance is built from the ground up with the minimum required components. It runs everywhere thanks to multiple build formats, including an installable live CD, a VMDK with OVF support, and an Amazon EC2 AMI.
Portable Linux is a tool that lets you create bootable USB and removable drives using popular Live CDs based on Casper (like the Ubuntu family of distributions). It sports some unique features. The live setups it creates let you use the remaining disk space on your USB drive to store and transport files between computers, as usual. If your distribution supports persistence, the files and settings you edit on your live Linux distribution are persisted across reboots. Finally, you can access the area used to store your files from within your Linux distribution.
