Build Linux is a toolset for assembling a custom Linux distribution entirely from source code, automating the process described by Linux From Scratch. It compiles every system component from upstream source, giving the builder full control over included packages and configuration.
The build process relies on a Makefile-driven orchestration that coordinates the entire sequence, using script-defined package recipes for each component. It employs chroot isolation to keep build artifacts separate from the host, and follows a stage-wise bootstrapping approach that first builds a minimal set of temporary tools before constructing the final system. After packages are installed, the system is hardened with configuration templates for logging, networking, and security.
The resulting distribution includes functional system services such as a system logger that collects kernel and daemon messages into configurable files, and a DHCP client that automatically obtains an IP address at boot. This makes the built system immediately usable without manual configuration of these common services.
