Kickstart 不工作

我正在尝试创建一个 kickstart 来自动化安装过程，但当安装结束时，我检查结果时什么都没有发生。我试图通过将 read 语句放在不同的地方来调试它，看看是否一切都运行正常。似乎所有变量都在那里，但当 setMask 函数执行时它会重新启动。任何帮助都将不胜感激。

exec < $curTTY > $curTTY 2> $curTTY

echo 'Specify the hostname to assign: '; read hostname
echo -n "Enter ip of ips (separated by spaces): "; read ip
echo -n "Enter ipv6 address: "; read ipv6

#Saving data
echo $hostname > /tmp/hostname
echo $ip > /tmp/ip
echo $ipv6 > /tmp/ipv6

%end

根据功能，似乎该--no-chroot选项可能导致此问题。或者，可能需要将根映像所在的路径附加到某些数据重定向的路径，通常类似于/mnt/sysimage/rootCentOS。因此，可以设置这样的变量并将其附加到必要时

rootfs=/mnt/sysimage/root
...
echo DEVICE=eth0 >> $rootfs/etc/sysconfig/network-scripts/ifcfg-eth0
...

除了删除--no-chroot选项之外，添加日志选项可能有助于获取有关故障的更多信息。

%post --log=/path/to/post/install/log.log

除了记录帖子的 chrooted 部分和非 chrooted 部分是否必要之外，还可以有多个%post部分，例如Redhat 的概述如下. 在部分复杂的情况下%post，将任务拆分为多个带有单独日志的后续脚本，对于确定 kickstart 文件问题的根本原因非常有价值。

除了拆分之外，%post如果您可以访问文件服务器或某种共享存储，您可以编写包含后期使用的函数的脚本，然后在后期部分安装/复制它们并调用相关函数。这将使您有机会测试一些脚本，而无需在调试时不断使用 kickstart 文件重建/重新安装，从而节省大量时间。
