4.1. Introduction

In this chapter, we will perform a few additional tasks to prepare for building the temporary system. We will create a set of directories in $LFS (in which we will install the temporary tools), add an unprivileged user, and create an appropriate build environment for that user. We will also explain the units of time (SBUs) we use to measure how long it takes to build LFS packages, and provide some information about package test suites.
