Leah Rowe 6b67e12428 lbutils/file: don't eintr loop fcntl
not indicated. the way we use it is basically like
stat, to check that a file exists / is a file.

just err the fuck out

nuance: SETLK is non-blocking (no wait).
we should loop on SETLKW, but we don't use that.
in this codebase, we use SETLK for locking a
tmpfile, but because of race conditions and
wanting to make another file quickly, we just
try again with a newly generated name, with a
certain number of retries, so we justt use SETLK

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.
