I thought I should let this list know what's been going on with
linux-libre and Gentoo.
Over the past few months (year actually - wow) I've been working on
getting linux-libre to work well with Gentoo (see
https://bugs.gentoo.org/show_bug.cgi?id=266157 for all the gory
Gentoo has a diverse user base, not all of whom would consider a
libre kernel as important, so simply replacing the kernels gentoo
has available wouldn't have been desirable or politically tenable.
So I went the Gentoo route and added a "USE flag" (the mechanism in
Gentoo to customise all sorts of options in software packages)
'deblob,' which if enabled pulls in the appropriate deblob script
for the kernel being installed and runs it. At the moment
deblob-check isn't being used, as it took too long, but after seeing
some problems with this approach (see wayne's email on this list)
it's probable we'll use it soon (also thanks enormously to the
speedups in recent versions of the deblob-check script).
This 'deblob' option has been integrated into Gentoo's core kernel
install scripts (kernel-2.eclass), which means that any Linux-based
kernel tarball which is available (and for which a deblob script is
available) for Gentoo can be automatically installed deblobbed. So
the realtime kernel and the hardened kernel are available in libre
variants for free in Gentoo. Which is super-cool :-)
So yeah, that's us. Anyone has any comments or questions ask away.
Note that I'm not a gentoo developer, but I help out quite a bit
where I can, and wrote the original deblob eclass functionality
which is now (in slightly modified form) in Gentoo.
Thanks again for all your good works guys.
