Where is the kernel source on the "Universal" x86

I just got my 2004.0 x86 Universal CD and i686 second CD. I tried following the stage 3 instructions, but I got to the place where I'm supposed to build the kernel, and none of the kernel sources appear to be on *either* CD! Do I have to download them separately, or are they "hidden" somewhere on the release CDs??

I'm having the same problem, did you also realize that on the i686 packages cd there are no xfree and kde packages ?

Only the sources for the vanilla kernel are on the cd. But be aware, the newest ebuild is for version 2.4.25 and the sources have version 2.4.24. So you have to go to /usr/portage/sys-kernel/ . There you type in emerge vanilla-2.4.24.ebuild . I'm not sure if the file there is vanilla- so just do an ls and see. The important thing is the 2.4.24 version at the end.

I recommend downloading them. ie. emerging them. Like stated previously, only vanilla sources are on the live cd.

/plug emerge gentoo-dev-sources

Well.. that's the thing... the LiveCDs are supposed to be entirely net-free. Kind of defies the purpose having to download stuff. I haven't gotten very far with them and ended up using 1.4, reemerging the entire xfree and xfce. Works now... but a long way coming.

Mine has KDE ... are you sure about that?

Yeah ... I see ... sort of. The documentation is confusing. I did 1.4 installs with some scripts I made from the documentation. I did the first attempt at 2004.0 by hand, following the documentation. I got to the point where it asked to emerge the kernel source and typed "emerge -k gentoo-sources" and it went out to the (unconnected) Internet and croaked.

Next question: what's the difference between the portage snapshot tarball on CD 1, the portage snapshot *tarball* on CD2 and what looks like a portage *tree* on CD2?

That was why I went for the new CDs as well. I don't mind downloading packages not on the CD; I use R, maxima, texmacs, lyx and a few others that aren't on the CDs, but it's a royal pain to download KDE, XFree86, openoffice and the mozilla collection on a dialup. Of the packages that I use regularly, only *one* -- R -- has significant performance benefits from optimal compilation. All the rest of the distro (and Red Hat, Debian/Knoppix distros as well) performs just fine with the default i686 binaries on every machine I've got, and I'm more or less unconvinced that even the i686 binaries offer any significant improvement over i386 binaries.

In other words, what they taught me in computer science courses remains true -- the two fundamental ways to improve performance are faster hardware and better algorithms. Everything else is insignificant in the shadow of those two factors.
