Extremely Cool Tool for Creating Live Linux USB Keys

Universal USB Installer by pendrivelinux.com is a really cool utility which automates the process of creating a live Linux USB key installation.  With this utility, you can easily transfer a Linux live CD image to a USB key.  It supports various versions of Ubuntu/Kubuntu/Xubuntu, Knoppix, GParted, and many others.

All you have to do is download the iso cd image of the live Linux system you want, then copy the Universal USB Installer program into the same directory as the .iso, and run it.

I created a bootable Ubuntu 10.4 USB key with this utility in a few minutes.  It also has an option to set a persistence option for the system it installs, meaning that, unlike with a CD, you can actually read/write data on the USB key and save your customizations/configurations between reboots.
