Flavio Villanustre writes "While looking for a portable live linux Distribution to run off a USB drive, I tried the latest version (1.2) of Damn Small Linux (DSL) and got pleasantly surprised.
DSL is a live, self contained but extensible, linux distribution that can run from USB drives, CD-ROM’s, mini CD-ROM’s (business card shaped) and any other read write or read only media. It can be installed in a hard drive and become a full Debian distribution should you need it.
The beauty of DSL resides on it’s size, extensibility and flexibility. Traditionally, when you thought of a live CD linux distribution, you thought of a static distribution. DSL is flexible and can use any available read write media to save customizations and additions."
