2. Important Changes for 2005.1

Security Updates

Gentoo Linux 2005.1 contains security updates to address GLSAs (Gentoo Linux Security Advisories) numbered 200503-18 to 200507-27.

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 2005.1 the PowerPC teams completed the first steps to merge the PowerPC 32-bit and PowerPC 64-bit development teams. This merge results in the use of a common profile. The ppc64 profiles can be found in /usr/portage/profiles/default-linux/ppc/2005.1/ppc64. You must choose a bit level for your userland. At the moment 32-bit and 64-bit are supported, a multilib userland will be supported in the near future. For each bit level we also support further sub-profiles for 970 (the JS20), 970/pmac (the G5), power3, power4 and power5. Please update your profile as described in .

Errata

Errata
32-bit userland and external kerenl modules.	Due to complications that arose from creating a 32-bit userland external kernel modules will not yet compile and function. The team is working on rectifying this issue.

Documentation Updates

Much consideration and time has been spent on the Gentoo Installation Handbook in order to get it more in sync with Gentoo 2005.1. 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 Linux 2005.1

Installing Gentoo Linux 2005.1

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

Each architecture offers three LiveCDs. The first one being a universal bootable LiveCD which can be used to install with or without an Internet connection. The second LiveCD is a non-bootable subarch-optimized Gentoo Reference Platform (GRP) LiveCD which contains precompiled binaries of popular programs such as X.org-x11 and KDE. The third LiveCD is a bootable minimal LiveCD that is smaller in size and includes only the basics needed to simply boot a machine.

At a minimum, the universal or minimal LiveCD is required to boot the machine and install Gentoo. The universal LiveCD 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 LiveCD requires an Internet connection to install Gentoo Linux.

There is one kernel available on both bootable cds. It will run on both, uniprocessor and multiprocessor systems. The kernel is based on linux-2.6.12 (vanilla-sources-2.6.12.2).

The LiveCDs are located on the mirrors as follows:

LiveCD Description	Location on Mirrors
Universal bootable LiveCD	/releases/ppc/2005.1/ppc64/installcd/install-ppc64-universal-2005.1.iso
Minimal bootable LiveCD	/releases/ppc/2005.1/ppc64/installcd/install-ppc64-minimal-2005.1.iso
Non-bootable GRP-/Packages CD	/releases/ppc/2005.1/ppc64/packagecd/packages-ppc64-64ul-2005.1.iso

Upgrading to Gentoo Linux 2005.1

If you already have a working installation of Gentoo Linux (Version 1.4, 2004.0 through 2005.0) there is no need to reinstall. You will automatically get Gentoo 2005.1 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 2005.1. 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.
