Toolchain Update

With Gentoo 2006.1, the x86 team has made big changes to the toolchain. It now contains the following versions:

  • sys-devel/gcc-4.1.1
  • sys-libs/glibc-2.4-r3
  • sys-devel/binutils-2.16.1-r3

For upgrading gcc from version 3 to version 4, please follow the instructions in the Gentoo Linux GCC Upgrade Guide.

X.Org Upgrade

With this release, version 7.0-r1 of X.Org X11 is used. This is the modular version of X. For upgrading from the monolithic version of (<7.0) , please follow the instructions in the Migrating to Modular X HOWTO. While version 7.1 is available, we decided not to use it, as a compatible version of the binary NVidia drivers had not been released at snapshot time.

Userland Updates

  • Catalyst, the Gentoo Release Metatool, is stable in Portage as version 2.0. To use Catalyst, simply emerge catalyst.

Documentation Updates

Much consideration and time has been spent on the Gentoo Installation Handbook in order to get it in sync with Gentoo 2006.1. Please note that it is a constant work in progress, and if any bugs are encountered, please refer them to the Gentoo Linux bugtracking system at .

3.  Upgrading and Installation of Gentoo 2006.1

Installing Gentoo 2006.1

The entire Gentoo Linux installation process is documented in the Gentoo Handbook.

The x86 release team offers a minimal InstallCD and a LiveCD. The first one being a universally bootable InstallCD which can be used to install only using an Internet connection. The LiveCD is useful for doing networkless installs. It will only work on machines that implement the i686 instruction set and higher.

There is only one kernel available on both bootable CDs. It will run on both, uniprocessor and multiprocessor systems. The kernel is based on the linux-2.6.17 series (gentoo-sources-2.6.17-r7). Please refer to the handbook for booting the CD.

The cds are located on the mirrors as follows:

InstallCD Description Location on Mirrors
Minimal bootable InstallCD /releases/x86/2006.1/installcd/install-x86-minimal-2006.1.iso
Bootable X-LiveCD containting the Gentoo Installer /releases/x86/2006.1/livecd/livecd-x86-installer-2006.1.iso

Upgrading to Gentoo Linux 2006.1

If you already have a working installation of Gentoo Linux (Version 1.4, 2004.0 through 2006.0) there is no need to reinstall. You will automatically get Gentoo 2006.1 if you sync your Portage tree and run emerge --update world. If you still have an installation with a Gentoo 1.2 profile it might make sense -- in some cases -- that you do a new installation.

There is also the possibility to update your system to a 1.4 profile from which you -- as already stated -- can easily get to Gentoo 2006.1. This update includes recompiling of glibc and some essential system packages; it will take a very long time (possibly longer as a complete re-installation) and it might also fail. So if you still have an installation with a Gentoo 1.2 profile, it's your decision whether you update or reinstall.
