Fedora 7 on a Stick
How to make a bootable version of Fedora 7 on a USB thumb drive. This information was passed along by a friend and based it on this article. The .sh is part of the LiveCD tools. (Note that syslinux is now included in F7-Test4 LiveCD). Fedora 7 now includes a "live" bootable CD image, which can be loaded to and booted from a USB stick. I.e. you can boot and run Fedora Linux without installing it to a hard drive, which makes it a great system and network troubleshooting tool. The process of copying the image to a USB drive is a little intricate, as you have to run it on Fedora 7 itself, which means you need a bootable CD to start with. Here's how to do it using a Windows system as the starting point. Requirements
