2.  Important Changes for 2006.0

Security Updates

Gentoo Linux 2006.0 contains security updates to address GLSAs (Gentoo Linux Security Advisories) numbered 200507-28 to 200601-14.

Individual GLSAs can be referenced by going to http://www.gentoo.org/security/en/glsa/glsa-$x.xml, and substituting $x with the desired GLSA number.

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

Profile Update

With Gentoo Linux 2006.0 the PowerPC team made rather big changes to the profile. The merge of the ppc32 and ppc64 profiles went forward. Furthermore the ppc32 profile has been changed in a way, that it offers a minimalistic generic profile for all purposes, located in /usr/portage/profiles/default-linux/ppc/ppc32. The release-dependent profile is optimized for desktop-usage and located in /usr/portage/profiles/default-linux/ppc/ppc32/2006.0. There are some subprofiles available for G3 and G4 processors, and G3/Pegasos and G4/Pegasos for the Pegasos Open Desktop Workstation. Please update you profile as described in .

Errata

Errata Workaround
pbbuttonsd fails to start. This tool gives some power and keyboard advantages to Apple Laptop and Desktop users. On some systems it fails to start, but that would not harm anything for the installation.
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.
The fan on some G4 Apple laptops don't work during installation. After the CD has booted you have to call modprobe therm_adt746x. This will load the appropriate kernel module for the fan-controler. The initial coldplug does not take care of it.

For information about how to change your profile please read .

Warning: Cascading profiles will only work with Portage >=2.0.51. Make sure to first upgrade to an appropriate version of Portage and then upgrade your profile!

Portage Updates

The Portage version included in this release is 2.0.54 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 2006.0. 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 Linux 2006.0

Installing Gentoo Linux 2006.0

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 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 requires an Internet connection to install from a stage1 installation tarball, but 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 linux-2.6.15.4 (gentoo-sources-2.6.15-r4). 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/2006.0/installcd/install-ppc-universal-2006.0.iso
Minimal bootable InstallCD /releases/ppc/2006.0/installcd/install-ppc-minimal-2006.0.iso
Non-bootable GRP-/Packages CD for generic PowerPC /releases/ppc/2006.0/packagecd/$subarch/packages-ppc-2006.0.iso
Non-bootable GRP-/Packages CD optimized for G4 /releases/ppc/2006.0/packagecd/$subarch/packages-g4-2006.0.iso

Upgrading to Gentoo Linux 2006.0

If you already have a working installation of Gentoo Linux (Version 1.4, 2004.0 through 2005.1) there is no need to reinstall. You will automatically get Gentoo 2006.0 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 2006.0. 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.
