For example, libreboot distributes GRUB/memtest86+/bucts/flashrom (and more) and comes with user-focused documentation and build scripts; libreboot is therefore made more 'user-friendly'. </li> </ul> <p> Libreboot is <b>not</b> a fork of coreboot, despite misconceptions of this fact. Libreboot (downstream supplier) is a parallel effort which works closely with and re-bases on the latest coreboot (upstream supplier) every so often. </p> <p> <b> As such, all new coreboot development should be done in coreboot, not libreboot! Libreboot is about deblobbing, and packaging coreboot in a user-friendly way, where most work is already done for the user! If, for example you wanted to attempt porting a new motherboard then you should do that in coreboot. Libreboot will (as a downstream) receive your change at some point in the future, in a future release. </b> </p> <p> <i>Libreboot</i> as a whole is the distribution distributed deblobbed. However, the core part is coreboot: libreboot's deblobbed coreboot tree is named <i>coreboot-libre</i> to distinguish it as a component of <i>libreboot</i>. (if that makes sense). </p> <h2> A 'stable' coreboot: </h2> <ul> <li> Coreboot uses the <a href="https://en.wikipedia.org/wiki/Rolling_release">rolling release</a> model (and it is therefore quite volatile; one day when you build coreboot, it may or may not work correctly on your machine). </li> <li> Libreboot changes less often (as far as the release model is concerned), focusing instead on 'tested' releases for <i>specific machines</i>. At any given time, it might also be possible to build ROM images for systems other than those officially supported. If you get your board to work (without violating the <i>"coreboot development goes in coreboot"</i> rule), then others could benefit from it. </li> </ul> <p> On the other hand, coreboot is also strict about what it accepts (merges) into the main git repository: most of the time, a lot of changes are under review at review.coreboot.org (as a way of encouraging as much further development as possible before accepting the patch). </p> <p> Meanwhile, libreboot is a lot less strict in this area and freely merges specific patches that are desirable, sometimes before they are merged into coreboot's main repository. </p> <p><a href="#pagetop">Back to top of page.</a></p> <hr/> <p> Copyright © 2014 Francis Rowe <info@gluglug.org.uk><br/> This document is released under the Creative Commons Attribution-ShareAlike 4.0 International Public License and all future versions.
