修改preseed文件定制ubuntu安装cd
针对一些常见需要手动配置的部分，进行修改使之自动。
不断完善中.................
1、跳过开始部分的语言和安装选项
所有ubuntu版本，均修改光盘根目录中isolinux/isolinux.cfg,修改timeout参数，如timeout 1
2、修改背景图片，替换isolinux中的splash.pcx
3、自动选择语言、键盘布局等，比较新的ubuntu版本，修改isolinux/text.cfg,接着seed文件，如下：
debian-installer/locale=en_US kbd-chooser/metuod=us console-setup/layoutcode=us
4、跳过网络选择和设置主机名那一步
# Network configuration.
d-i netcfg/choose_interface select auto
d-i netcfg/dhcp_failed note
d-i netcfg/dhcp_options select Do not configure the network at this time
d-i netcfg/get_hostname string keqi-server
d-i netcfg/get_domain string keqi-server
5、使用root登录并使用弱密码时取消提示
# Account setup
d-i passwd/root-login boolean root
d-i passwd/root-password password 123456
d-i passwd/root-password-again password 123456
d-i user-setup/allow-password-weak boolean true
d-i passwd/make-user boolean false
d-i user-setup/encrypt-home boolean false
