请问是什么原因？其中rcS的权限我也修改了，请指教

maybe your nfs file system has some problems or and did you add your nfs directory to /etc/exports in your host and give the target machine the enough access previliges?

看看你的nfs rootfs目录的执行权限
第二个问题可以 通过在你的rootfs  dev 下创建节点的方法来解决

同样的问题，期待高人指点。

nfs已经挂载上了，但是其中的/etc/rc.d执行权限有问题。
后面的问题可以修改/etc/initab来解决
或者在/dev下创建对应节点，或者做个链接
