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.

I have an array of such machines...
Of course it depends on how many modules, etc, but it'll probably take 1-1.5 hrs for the kernel and maybe 3-4 hours for the modules, and even make deps will probably take 30 minutes.
With more RAM these times would improve considerably. But, my main machine is a PII 333MHz and it seems that performance doesn't improve much above 300-400MB RAM. What I mean is that the processor becomes the bottle-neck above that.
I have often thought of doing this, but never got around to it.
So, this evening I wiped my laptop with Slack 10 (2.4.26) and did a fresh install of the plain 2.4.26 kernel.
Sometime this evening I'll compile a custom kernel for it on another box and transfer the stuff that carboncopy
I Just did as carboncopy said, except I didn't move the System.map file over, and it works.
on a Dual 2.8GHz HTXeon 400MHz fsb box it took 5 min and 35 sec to make bzImage
This while processing two Folding@Home work units. The F@H work units didn't show
any sign of processing slower because of this compiling activity.
Thanks carboncopy for getting me in gear, I have wanted to do this for some time.
The dual Xeon box is the most powerful box I have, and I always need a special kernel for other slower units.
And really don't like to compile a kernel on the laptop due to the heat and the fan noise that goes
with the process. The laptop has a 2.4GHz P4 and it runs hot as *%@^ just by being turned on. :0
