解决rdo安装过程中，puppet的timeout问题

（一）错误日志：

http://storageboy.com/2013/04/25/quick-tip-on-installing-and-running-redhats-openstack-distro/

ERROR : Error during puppet run : err:

/Stage[main]/Packstack::Netns/Exec

[netns_dependecy_install]/returns: change from notrun to 0 failed: Command exceeded timeout at /var/tmp/packstack/f93b67f77de342619ed9805ecc823c8d/modules/packstack/manifests/netns.pp:13

（二）解决方法：

# vim /usr/lib/python2.6/site-packages/packstack/puppet/modules/packstack/manifests/netns.pp

在command => "yum update -y kernel iputils iproute"

上面加一行timeout => 3600，

然后从新执行rdo安装过程

执行前提先kill掉进程里面的flock ，puppet，yum进程
