Before being merged with the commitdc6e1f32c1("Import website-build to build the GNU Boot website."), website-build was a separate git repository. And so, even after the merge, until the commit20d122e94a("website-build: use website from local git repository."), it still worked in the same way and still downloaded the website from git. This prevented merging the website and website-build directories together as the GNU Boot repository also needed to be a valid Untitled website repository as well. Now after this commit, the website is built from the same git tree, so we can simply adjust the build scripts to be able to move things around. In addition of making things more clear for contributors, it also simplify the migration to haunt as with haunt we typically have the haunt.cfg (and the autotools build code if needed) code in the top directory and the markdown files in a subdirectory.

How do I know what version I'm running? {#version}
|
|
========================================
|
|
|
|
If you are at least 127 commits after release 20150518 (commit message
|
|
*build/roms/helper: add version information to CBFS*) (or you have any
|
|
*upstream* stable release of libreboot after 20150518), then you can
|
|
press C at the GRUB console, and use this command to find out what
|
|
version of libreboot you have:
|
|
|
|
cat (cbfsdisk)/lbversion
|
|
|
|
Alternatively, you may run this command in GRUB:
|
|
|
|
lscoreboot
|
|
|
|
If you're using SeaBIOS, information is provided there aswell.
|
|
|
|
This will also work on non-release images (the version string is
|
|
automatically generated, using `git describe --tags HEAD`), built from
|
|
the git repository. A file named `version` will also be included in the
|
|
archives that you downloaded (if you are using release archives).
|
|
|
|
If it exists, you can also extract this `lbversion` file by using the
|
|
`cbfstool` utility which libreboot includes, from a ROM image that you
|
|
either dumped or haven't flashed yet. In your distribution, run
|
|
cbfstool on your ROM image (`libreboot.rom`, in this example):
|
|
|
|
./cbfstool libreboot.rom extract -n lbversion -f lbversion
|
|
|
|
You will now have a file, named `lbversion`, which you can read in
|
|
whatever program it is that you use for reading/writing text files.
|
|
|
|
For git, it's easy. Just check the git log.
|
|
|
|
For releases on or below 20150518, or snapshots generated from the git
|
|
repository below 127 commits after 20150518, you can find a file named
|
|
*commitid* inside the archives. If you are using pre-built ROM images
|
|
from the libreboot project, you can press C in GRUB for access to the
|
|
terminal, and then run this command:
|
|
|
|
lscoreboot
|
|
|
|
You may find a date in here, detailing when that ROM image was built.
|
|
For pre-built images distributed by the libreboot project, this is a
|
|
rough approximation of what version you have, because the version
|
|
numbers are dated, and the release archives are typically built on the
|
|
same day as the release; you can correlate that with the release
|
|
information in [release announcements on the news page](/news/).
|
|
|
|
For 20160818, note that the lbversion file was missing from CBFS on GRUB
|
|
images. You can still find out what libreboot version you have by
|
|
comparing checksums of image dumps (with the descriptor blanked out with
|
|
00s, and the same done to the ROMs from the release archive, if you are
|
|
on a GM45 laptop).
|
|
|
|
There may also be a ChangeLog file included in your release archive, so
|
|
that you can look in there to figure out what version you have.
