7.1. Introduction
Chapter 7 moves into the target environment by entering chroot and building enough of the utility set from within that system to continue the rest of the build.
Goal: enter the target system with
chroot, then build the utilities needed in that environment so the rest of the system can be built from inside it.
Chapter 6 established a minimal working base. Chapter 7 transitions from cross-built staging into target-native operation by entering chroot and completing the utility builds needed to continue the remaining system work from inside the target tree.
This chapter is focused on two outcomes:
- establish a reliable
chrootenvironment that behaves predictably for package builds; - build the core utilities needed for the remaining system build so the process no longer depends on temporary bootstrap assumptions.
By the end of this chapter, the target system should be capable of continuing package work from within its own environment, with sufficient utility coverage in place to build the rest of the system.
