Ars Technica: Linux on a Flash Drive

“How many times have you sat at a computer and thought, If Linux
was installed on this box I could… Wish no longer. Instead of
carrying around bulky Live CDs or an external hard drive, how about
Linux in your pocket? The combination of a USB key and SLAX, the
Linux distro used in this example, is a powerful combination when
it comes to troubleshooting and spreading the word about Linux. The
ability to boot the key, browse the computer’s hard drive (SLAX has
NTFS support built in), and then locate and burn a file to CD can
be very helpful, especially with a computer that is on its last
legs. So grab your key and come with me, when were done you’ll have
a new tool to help out in the computing trenches.
