2.  Important Changes for 2006.1

Security Updates

Gentoo 2006.1 contains security updates to address GLSAs (Gentoo Linux Security Advisories) numbered 200601-15 to 200608-17.

Individual GLSAs can be referenced by going to$x.xml, and substituting $x with the desired GLSA number.

For more information, please consult the the Gentoo Linux Security Project home page.

Toolchain Update

With Gentoo 2006.1 the PowerPC team made big changes to the toolchain. Now it 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

On Gentoo PowerPC the version 7.1 of X.Org X11 is used. This is the modular version of X. For upgrading, please follow the instructions in the Migrating to Modular X HOWTO.

Airport Express supported by kernel

With the Linux kernel 2.6.17 the Broadcom Chipset used in Apples Airport Express Wireless LAN network interfaces is officially supported. With Gentoo 2006.1 this kernel version is used by default on the PowerPC platform.


Errata Workaround
pbbuttonsd does not start. This tool gives some power and keyboard advantages to Apple Laptop and Desktop users. During the release QA-phase we found out, that recent versions of pbbuttonsd depend on a c++-library which is not available on the InstallCD. We removed pbbuttons from the InstallCD for this release.
There is no bootsplash As the bootsplash, known from previous releases, consumes 25 MB of disk-space on the CD, we decided to leave it out in order to hand you a smaller ISO. Furthermore the in-kernel libc, klibc, refuses to compile on the PowerPC-platform properly. This is a known bug with some major kernel-changes on PowerPC during the last kernel-releases.
Troubles booting on OldWorld machines with BootX Some OldWorld machines refuse to boot the 2006.1-CD with BootX. In this case, use the 2006.0 CD for booting, but you are able to install Gentoo 2006.1 with the appropriate stages.
Serial output on the Pegasos does not work Another command in SmartFirmware is needed. Use boot cd boot/pegasos console=ttyS0,115200 init=/linuxrc looptype=squashfs loop=/image.squashfs udev nodevfs cdroot root=/dev/ram.

Critical Package Updates

Important package-versions in this release:

pegasos Supports Genesi's Pegasos I and II Open Desktop Workstation, with multiprocessor support.

For information about how to change your profile please read .

Portage Updates

The Portage version included in this release is 2.1 and the ChangeLog can be found via our online CVS repository.

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 PowerPC release team offers three InstallCDs. The first one being a universal bootable InstallCD which can be used to install with or without an Internet connection. The second InstallCD is a non-bootable subarch-optimized Gentoo Reference Platform (GRP) CD which contains precompiled binaries of popular programs such as, KDE, and GNOME. The third InstallCD is a bootable minimal CD that is smaller in size and includes only the basics needed to simply boot a machine.

At minimum, the universal or minimal InstallCD is required to boot the machine and install Gentoo. The universal InstallCD does not require an Internet connection to install from a stage3 installation tarball. The minimal InstallCD requires an Internet connection to install Gentoo Linux.

There are two 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-r5). Please refer to the handbook for booting the CD.

The InstallCDs are located on the mirrors as follows:

InstallCD Description Location on Mirrors
Universal bootable InstallCD /releases/ppc/2006.1/installcd/install-ppc-universal-2006.1.iso
Minimal bootable InstallCD /releases/ppc/2006.1/installcd/install-ppc-minimal-2006.1.iso
Non-bootable GRP-/Packages CD for generic PowerPC /releases/ppc/2006.1/packagecd/$subarch/packages-ppc-2006.1.iso
Non-bootable GRP-/Packages CD optimized for G3 /releases/ppc/2006.1/packagecd/$subarch/packages-g3-2006.1.iso
Non-bootable GRP-/Packages CD optimized for G4 /releases/ppc/2006.1/packagecd/$subarch/packages-g4-2006.1.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.
