CentOS 是 RHEL（Red Hat Enterprise Linux）源代码再编译的产物，而且在 RHEL 的基础上修正了不少已知的 Bug ，相对于其他 Linux 发行版，其稳定性值得信赖。
可是红帽企业Linux 6.0 已经发布有些日子了，但是令人失望的是 CentOS 6 目前还没有任何动静，会在2011年愚人节发布吗？如果幸运的话，当然，我们不做任何指望。
CentOS 6 still needs a few weeks worth of work before its ready for release, so once 5.6 is released we will refocus on 6.0." He also explains the reasons behind the delay: "It's a new system compared to CentOS 5, so it's just the time taken to audit sources and workout individual package policy that takes time. Also CentOS 6 is going to have more packages than any other previous CentOS release, making things even slower. Having said that, we have had a few more people start contributing and there has been a general favourable turn in the passive user base. These things take time to evolve and I feel the next few months should see an even larger contributor base come together." Patience seems to be an important virtue for all those who eye CentOS 6, but it should be worth the wait: "There are quite a few interesting things coming up. A newer base kernel with some enhancements in performance and management tools, a newer virtualisation layer, newer Ruby and Python stacks with lots of developer-oriented features and packages. Overall more modern and much improved desktop experience."
