2. Introduction
Welcome to the CentOS 4.9 release. CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by our Upstream OS Provider (UOP)1.
CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.) CentOS is a Free Operating System.
CentOS 4.9 is the ninth update to the CentOS 4 distribution series. It contains bugfixes, updates and new functionality. This is the last expected set of changes to add new functionality to the CentOS 4. We will continue to provide security updates and bug fixes for CentOS 4 until its End-of-Life scheduled for February 29, 2012.
Before reading any further we advise you to read the UOP release notes. The rest of this document is an addendum to those notes, and primarily covers CentOS-specific issues.
3. Known Issues
|
The upstream provider did not respin media for the 4.9 release and therefore the CentOS project will also not respin our install media. Installs moving forward will be off the 4.8 media and an upgrade will move you from version 4.8 to version 4.9. We do this to maintain compatibility with 3rd party kernel drivers which are designed to be installed as part of the installation process. - There is a requirement to swap in CD-1 during the install phase of CD-4 during some installs when the comps RPM is required to be installed. This is because to get a minimal install with only one CD, the comps RPM has been moved to CD-1. We are sorry for the inconvenience, but we think having comps on CD-1 is the best solution to this issue.
An upstream bug #497499 with the 3c59x Ethernet driver has been encountered during testing. The specific hardware tested was "3Com Corporation 3c556B CardBus [Tornado]". No workaround is known for this bug.
CentOS adds i586 support to CentOS 4 that is not available upstream. There are issues with the i586 support on the CentOS 4.8 install media. If you are using CentOS 4 on an i586 machine, you should be able to use a modified installer from i586.centos.org. Please see this link for more information on i586 on CentOS 4.8.
This is expected to be the last normally scheduled Point Release during the Deployment Life Cycle Phase for CentOS 4. What this means is that the prior release (4.8) was expected to be the last major update to add new hardware support. New deployments on new hardware going forward should instead use a version of CentOS that is in the Full Support Phase. Currently only the CentOS 5.x series is in the Full Support Phase.

5. Community Involvement
As a CentOS user there are various ways you can help out with the CentOS community.
5.1. Special Interest Groups
CentOS consists of different Special Interest Groups (SIGs) that bring together people with similar interests. The following SIGs already exist:
Artwork - create and improve artwork for CentOS releases and promotion
Promotion - help promoting CentOS online or at events
Virtualization - unite people around virtualization in CentOS
And we encourage people to join any of these SIGs or start up a new SIG, eg.
- Hardware compatibility - provide feedback about specific hardware
- QA - help out with fixing bugs and testing new releases
- RPM Packaging - contribute new useful RPM packages
- Translation - help translating the documentation, website and wiki content
5.2. Mailinglists and Forums
Another way you can help out others in the community is by actively helping and resolving problems that users come up against in the mailinglists and forums.
5.3. Wiki and website
Even as an inexperienced CentOS user we can use your help. Because we like to know what problems you encountered, if you had problems finding specific information, how you would improve documentation so it becomes more accessible. This kind of feedback is as valuable to others as it would have been to you so your involvement is required to make CentOS better.
So if you want to help out and improve our documentation and wiki, register on the wiki and subscribe to the centos-docs mailinglist.
