LINUX DISTRIBUTION CentOS has released version 6 of its free enterprise oriented operating system based on Red Hat Enterprise Linux (RHEL).
CentOS 6 follows in the footsteps of RHEL version 6.0, which Red Hat released at the tail end of 2010. CentOS aims to offer upstream binary compatibility with RHEL and as always the project says that most of the changes it makes to packages are to remove Red Hat branding.
As CentOS 6 is essentially an unbranded free version of RHEL 6, its features are almost identical. Red Hat decided to focus on virtualisation for RHEL 6 with support for non-uniform memory access architecture and 100TB file systems by supporting the XFS file system. All of that was announced by Red Hat back in November 2010 and it started the timer on the arrival of CentOS 6.
That CentOS 6 timer has been ticking for some time, certainly longer than usual, and back in May Red Hat announced RHEL 6.1. Upon announcing CentOS 6, Karanbir Singh said, "Since upstream [RHEL] has a 6.1 version already released, we will be using a Continuous Release repository for 6.0 to bring all 6.1 and post 6.1 security updates to all 6.0 users, till such time as CentOS-6.1 is released itself. There will be more details about this posted within the next 48 hours."
As CentOS 6 is a new major version, it is recommended that CentOS 4.X and CentOS 5.X users wanting to upgrade do a complete reinstall. µ
