系统环境：fedora13, linux 2.6.31.5-127.fc12.i686.PAE, gnome
核心操作：关闭selinux
以前使用fedora12及更早的fedora版本，安装chrome都非常正常，安装后，就可以正常启动运行。但这次，突然出问题了，从系统菜单里启动，老半天没有一点反应，查看进程，有chrome进程，看来是有错误了。于是杀死进程，命令行启动，看看究竟是什么错误消息。
/usr/bin/google-chrome: /lib/libz.so.1: no version information available (required by /usr/bin/google-chrome)
/usr/bin/google-chrome: /lib/libz.so.1: no version information available (required by /usr/bin/google-chrome)
Failed to move to new PID namespace: Operation not permitted
习惯性的拿错误消息问google，结果全是英文页面，看了两个，好像也没有说出来最终的解决方法。那就是自己捣腾一下，说不定就解决了。
上面两行错误消息，看不出来名堂，但下面的条里 not permitted，没权限，怀疑是否是不是selinux的原因，但没有看到selinux消息报告，所以之前没有想到这里，印象中sellinux是启动的，fedora13安装后，selinux就是启动的，经常会造成一点问题，由于对selinux并不熟悉，出问题时只好关掉。扯远了——不管是不是，关掉看看。
setenforce 0
再从命令行里启动，好了，chrome还给一个对话框，大意说启动失败了，是不是要报告错误，选择跳过，然后是就正常的询问是否从其它浏览器里导入设置，因为firefox正在启动中，无法完成导入，也跳过。接下来就是跟平时无两样的chrome。
从命令行终端里拷出来从安装到问题解决的整个过程的消息，稍做删减，帖在下面，以备查阅。
