From June 2023 to June 2024, my focus was pretty much focused purely on auditing of the build system, lbmk. This is what Libreboot uses to build itself, and it's what releases are built with. It's basically a source-based package manager that downloads, patches and builds all the sources, to make coreboot images for installation.
My auditing removed bloat: Libreboot 20230625's lbmk was about 3300 lines of bash. *Today's* lbmk is 1096 lines of sh, with *more features* and just works much better.
