Leah Rowe 7c6c9ff547 tree.sh: delete individual target builds if needed
Detect when a config changes. This is done even if the
entire tree doesn't change.

This is already done per-tree if files change, but
individual project files don't change.

For example, if a grub.cfg changes, the given cached
build for that GRUB tree isn't deleted. Same thing if
a given U-Boot config doesn't change.

This patch fixes a longstanding design flaw of lbmk,
making auto-re-builds more reliable. This complements
another recent change, that deletes all target builds
of a given tree when the tree changes.

Libreboot

Documentation: libreboot.org
Support: #libreboot on Libera IRC

Libreboot provides libre boot firmware on supported motherboards. It replaces proprietary vendor BIOS/UEFI implementations, by

  • Using coreboot to initialize the hardware (e.g. memory controller, CPU, etc.) while minimizing unwanted functionality (e.g. backdoors such as the Intel Management Engine)
  • ... which runs a payload such as SeaBIOS, GRUB, or U-Boot
  • ... which loads your operating system's boot loader (BSD and Linux-based systems are supported).

Why use Libreboot, and what is coreboot?

A lot of users who use libre operating systems still use proprietary boot firmware, which often contain backdoors and bugs, hampering user freedom and right to repair.

coreboot provides libre boot firmware by initializing the hardware then running a payload. However, coreboot is notoriously difficult to configure and install for most non-technical users, requiring detailed technical knowledge of hardware.

Libreboot solves this by being a coreboot distribution (in the same way that Alpine Linux is a Linux distribution). It provides a fully automated build system that downloads and compiles pre-configured ROM images for supported motherboards, so end-users could easily fetch images to flash onto their devices.

Libreboot also produces documentation aimed at non-technical users and excellent user support via IRC.

Contribute

You can check bugs listed on the bug tracker.

You may use Codeberg pull requests to send patches with bug fixes or other improvements. This repository hosts the code for the main build system. The website lives in a separate repository.

Development is also done on the IRC channel.
