Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

with the price of RAM not being not 2 xpensive .... why arent there any systems (2 my knowledge) where the complete OS is copied from a cheap ,slow hard-disk into a few GB's of cheap but many times faster RAM ... with a not mega fast processor .... that would be the same as tmpfs or boot disks where its all in RAM ....
That would I guess result in a system where a very fast processor & disk aren't necessary 4 a fast system ... the most expensive thing (although still quite xpensive at the moment) would be the RAM ....?
Or did I overlook the ovoius problem... ?
Can't store it permenantly... Would have to copy everything over on reboot. There is a program called RamDISK I believe it is, where you can put programs on your ram and then on shutdown it stores all the data in an .img file. Then on reboot it loads the .img file into your system memory. That would probably work...
What you are talking about is completely possible. It is (like michaelk said) a LiveCD, but not on a CD.
That is what I do on my embedded devices. The root file system is mounted on a RAM disk, and directories that need to survive a reboot (/etc mainly) are mapped to partitions on a storage device of some type (I use a Compact Flash card).
It is a VIA EPIA Mini-ITX motherboard with a solid state power supply and a 32 MB Compact Flash on the IDE chain to hold the boot initrd image/kernel and the /etc directory.
It runs a embedded version of Slackware I created that boots from a 8 MB compressed image that decompresses into a 32 MB RAMDISK. Which has telnet, FTP, SSH servers, plus network diagnostics (tcpdump, nmap, ettercap, etc).
I use them as remote network diagnostic machines, I drop one at a location I am doing some work on, and then I can control it from the main office to run tests on the remote network, simulate load, etc.
I am currently working on a version that can be used as a set top box for multimedia applications in a home network (playing videos and MP3s) with 802.11 support.
In addition to my day job, so to speak, I run a small company that builds computers for local companies, and I have been thinking of looking into mass producing them and possibly selling them, but for the time being they are just for personal use.
