关于Cobbler安装Ubuntu的记录。
01：加载系统镜像
通过XFTP将系统镜像上传到cobbler服务器的/tmp目录下
挂载镜像到/mnt目录
~]# mount -t iso9660 -o loop /tmp/ubuntu-18.04-server-amd64.iso（镜像全名） /mnt
在web端加载镜像并添加KS脚本文件
02：添加镜像
03：编辑ks文件
04：对应ks文件和镜像关系
05：同步设置
06：ks文件模板

# of the disks (which may not be visible when preseed/early_command runs).
# d-i partman/early_command \
# string debconf-set partman-auto/disk "\$(list-devices disk | head -n1)"
