This is the Gentoo Handbook, an effort to centralize Gentoo/Linux information. This handbook contains the installation instructions for an Internet-based installation and parts about working with Gentoo and Portage.

Installing Gentoo

In this part the reader learns how to install Gentoo on a system.

About the Gentoo Linux installation
This chapter introduces the installation approach documented in this handbook.
Choosing the right installation medium
It is possible to install Gentoo in many ways. This chapter explains how to install Gentoo using the minimal Installation CD.
Configuring the network
To be able to download the latest source code, networking will need to be configured.
Preparing the disks
To be able to install Gentoo, the necessary partitions need to be created. This chapter describes how to partition a disk for future usage.
Installing the Gentoo installation files
Gentoo installs work through a stage3 archive. In this chapter we describe how to extract the stage3 archive and configure Portage.
Installing the Gentoo base system
After installing and configuring a stage3, the base system is set up so that a minimal environment is available.
Configuring the Linux kernel
The Linux kernel is the core of every distribution. This chapter explains how to configure the kernel.
Configuring the system
Some important configuration files need to be edited. In this chapter an overview of these files is provided and an explanation on how to proceed.
Installing system tools
In this chapter some important tools are selected and installed.
Configuring the bootloader
In this chapter the right bootloader is installed and configured.
Finalizing the installation
The installation is now almost done. The last finishing touches are documented in this chapter.

Working with Gentoo

A Portage introduction
This chapter explains the "simple" steps a user definitely needs to know to maintain the software on his system.
USE flags
USE flags are a very important aspect of Gentoo. In this chapter, readers learn to work with USE flags and understand how USE flags interact with their system.
Portage features
Discover the features Portage has, such as support for distributed compiling, ccache and more.
Init script system
Gentoo uses a special initscript format which, amongst other features, allows dependency-driven decisions and virtual initscripts. This chapter explains all these aspects and explains how to deal with these scripts.
Environment variables
With Gentoo environment variables can be easily managed. This chapter explains how to do that, and also describes frequently used variables.

Working with Portage

Files and directories
To know Portage in-depth, first learn where it stores its files and data.
Variables
Portage is completely configurable through various variables that can be set in the configuration file or as environment variable.
Mixing software branches
Gentoo provides software separated in several branches, depending on stability and architectural support. "Mixing Software Branches" explains how these branches can be configured and how to override this separation individually.
Additional tools
Portage comes with a few extra tools that might make the Gentoo experience even better. Read on to discover how to use dispatch-conf and other tools.
Custom portage tree
This chapter gives some tips and tricks on how to use a custom Portage tree, how to synchronise only the categories necessary, inject packages and more.
Advanced features
As times goes by, Portage evolves and matures further and further. Additional features are continuously being put in - many of these are only of use by more advanced users. This chapter will go into more detail of these specific features.

Gentoo network configuration

Getting started
A guide to quickly get the network interface up and running in most common environments.
Advanced configuration
Here we learn about how the configuration works - this is prerequisite knowledge before continuing with modular networking.
Modular networking
Learn how to choose different DHCP clients, setting up bonding, bridging, VLANs and more.
Wireless
Configuring Gentoo for wireless networks
Adding functionality
Adventurous users can add their own functions to the networking tools.
Dynamic management
For laptop users or people who move their computer around different networks.
