Today at the go / no-go meeting[1] we decided to slip the Alpha by one week. This slip is needed to verify blocker bug fixes and validate new builds of software necessary to fix those bugs. We are confident that the fixes we have are valid, however we do not have enough time to prove them valid. We will spend the next few days doing that validation. In the mean time builds will continue to be pushed to updates-testing for 13, and even to 13 stable, however critical path packages might not be
pushed unless they are fixing a release blocking issue. Once we've validated all the fixes we will do more frequent pushes to 13 stable.
At this time we are not adjusting later milestone dates, as with no frozen rawhide we are not taking away any developer time.

首先，我得为取的这个标题道歉，因为相关的介绍很多，但是又能有多少人直接认知它呢？
2001年上半年，美国国家安全局向开放源码社区发布了一个安全性增强型版本的 Linux （Security-Enhanced Linux ，SELinux）包括所有代码！到现在，可以毫不夸张的说，它成了linux服务器维护员们的一块心病，到底是打开呢？还是关闭？打开的话由于它过于复杂，又缺乏有效的配置工具（知道近几年来才陆陆续续的出现一些）。不打开悬着的心放不下，因为关闭它后，裸linux的安全直下一个等级。
当别人打电话给我问“新装的linux为什么其他机器访问不了？ftp访问不了？Home目录下的应用访问不了？”的时候，我的第一句话就是问“SELinux打开了没有？”，相信这也是很多管理员的回答，但是作为我个人来说，还是比较钟情它的，很多服务器一直是开着的。在这里我还是建议，不要彻底的关掉了，至少打开到Permissive的方式（只记录风险操作，并不阻挡）！
至于它的工作原理，个人认为说的还全面的这里有：揭开 SE Linux 的秘密，请特别关注他的参考资料。要进去读之后才知道真正的linux。我这里就不翻版了！
以Redhat为例，RHEL4被作为试验品，有15个可由应用程序访问的目标程序组。然而，在RHEL5之中目标程序组达到了200个，引用Redhat的Walsh的话说就是：“RHEL5的目标是让SELinux无处不开。”！由此他们在RHEL5中引入了SELinux故障排解器(Troubleshooter)，故障排解器(Troubleshooter)也被称为故障排解集合(settroubleshoot)，是一个为存取向量高速缓存(AVC)消息监视稽核记录文件的工具。
