With Gentoo 2006.1 the PowerPC team made big changes to
the toolchain. Now it contains the following versions:
For upgrading gcc from version 3 to version 4, please follow the
instructions in the Gentoo Linux GCC
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
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
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
|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:
There are two kernels on the InstallCD:
||Supports uniprocessor and multiprocessor 32-bit Apple PowerPC
||Supports Genesi's Pegasos I and II Open Desktop Workstation,
with multiprocessor support.
For information about how to change your profile please read .
The Portage version included in this release is 2.1 and the ChangeLog
can be found via our online CVS repository.
- Catalyst, the Gentoo Release Metatool, is stable in Portage as
version 2.0. To use Catalyst, simply emerge catalyst.
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 .
Upgrading and Installation of Gentoo 2006.1
Installing Gentoo 2006.1
The entire Gentoo Linux installation process is documented in the Gentoo
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 X.org-X11, 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
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:
||Location on Mirrors
|Universal bootable InstallCD
|Minimal bootable InstallCD
|Non-bootable GRP-/Packages CD for generic PowerPC
|Non-bootable GRP-/Packages CD optimized for G3
|Non-bootable GRP-/Packages CD optimized for G4
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
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.
