CentOS 6.2 Release Notes

2. Introduction

Welcome to the CentOS 6.2 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 vendor's redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.)

We have decided not to follow the UOP's usage of Installation Codes. All 'channels' are available to the System Administrator at time of installation.

Similar to the practice of the upstream vendor, there is no supported path to 'upgrade' an installation of a prior major CentOS release (presently CentOS 5 or CentOS 4) to a new major release. This is not a CentOS imposed limitation, but rather reflects the upstream's approach on this matter. People who feel adventuresome and want to experiment are reminded to take and test backups first. As a note to people who attempt the upgrade in spite of this warning, such as by the unsupported upgradeany option from the media install command line, please note that you will need to manually retrieve the current centos-release package, manually do a rpm -e --nodeps removal of the prior centos-release package, and then manually install the CentOS 6 centos-release package, before yum can have any chance of working properly.

The continuous release ( CR ) repository makes generally available packages that will appear in the next point release of CentOS, on a testing and hotfix basis until formally released.

Please read through the other sections before trying an install or reporting an issue.

8. How to help and get help

As a CentOS user there are various ways you can help out with the CentOS community. Take a look at our Contribute page for further information on how to get involved.

8.1. Special Interest Groups

CentOS consists of different Special Interest Groups (SIGs) that bring together people with similar interests. The following SIGs already exist:

And we encourage people to join any of these SIGs or start up a new SIG, e.g.

8.2. Mailinglists and Fora

Another way you can help others in the community is by actively helping and resolving problems that users come up against in the mailing lists and the fora.

8.3. 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 or subscribe to the centos-docs mailing list.
