I was struggling with serveal bugs in CentOS 6 (Networkmanager,dhclient,Bind, and even more.
The CentOS-6.0 Continuous Release ( CR ) repository is now available on mirror.centos.org. This repository contains rpms to be included in the next CentOS-6.x release ( 6.1 ). Because these include security and bugfix updates, we strongly recommend everyone using CentOS-6 install and update their system using this repository.
Just wanted to share this!
