Knoppix is a lightweight Linux distro that is anything but light in its features and functions.
It equals or exceeds the performance of all the desktop varieties I run in Ubuntu and Linux Mint. It also could easily replace the portability on a stick I get with Puppy Linux.
Knoppix, much like Puppy Linux, provides a fully functional Linux distro that boots from a DVD or USB drive. Both save user settings and downloaded software added to the mix.
This persistent memory feature, unlike regular live distro sessions, lets you carry a complete Linux desktop with all of your files and special application settings in your pocket to run on any computer. You also can run Knoppix as your primary operating system as if it were installed on a hard drive.
Knoppix runs from a Live DVD or USB boot that is not designed for permanent hard drive installation.
