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 a tmpfs set up for /tmp, and it works. However, it initially has a 96MB maximum capacity, causing swap usage from applications. My laptop only has 192MB of ram, so this is bad. I'd like it to initially use less ram(like around 16MB) instead of 96MB.
There doesn't seem to be an option for this. Is this possible through kernel recompiling?
Or to state that another way - with 192 Meg of RAM you probably should *not* be using tmpfs for /tmp
tmpfs by design will use page cache and hence be subject to swapping. You can limit the (maximum) size of it, but that is rarely likely to be a good idea.
