Linux without a hard drive

Modern Linux distributions require around 100 megs to 200 megs of hard disk space to install. But is it
possible to run Linux on a system without a hard drive? Yes it is.
The Linux Router Project is a full-featured Linux distribution that fits on one diskette. It was made for
routers, and use modules to add the software packages you need, including DNS servers, Web servers, email
and routing. You can find more information on the Linux Router Project at http://www.linuxrouter.org
