关于suse 11 sp3 自动安装的问题---重启自动安装

我使用dhcp+tftp+http实现suse 11 sp3自动安装，但是需要安装的主机设置为PXE第一启动项，自动安装完成后重启后又开始安装，陷入一个重复安装的情况，官网增加一个配置，可是不知道如何处理，谢谢。链接如下：

A problem you might run into if you do installation via PXE is that the installation will run into an endless loop, because after the first reboot, the machine is doing PXE boot again and restarts the installation instead of booting from hard disk for the second stage of the installation.
This problem can be solved in different ways. One way is to use an http server to provide the AutoYaST profile. And, instead of a static profile, run a CGI script on the Web server that provides the profile and changes the TFTP server configuration for your target host. Then the next PXE boot of the machine will be from hard disk by default.
Another way is to use AutoYaST to upload a new PXE boot configuration for the target host via the profile:

true

DEFAULT linux
LABEL linux
localboot 0
