ubuntu livecd isolinux的定制

启动部分的菜单,显示内容等是在gfxboot-theme-ubuntu源码中,

apt source gfxboot-theme-ubuntu gfxboot

cd gfxboot-theme-ubuntu*/

make DEFAULT_LANG=zh_CN

sudo cp -af boot/* ../live-cd/isolinux/

参考:

https://help.ubuntu.com/community/LiveCDCustomization

如果是单纯的不显示语言选择窗口则可以通过修改配置文件来解决:

1.解压isolinux中的bootlogo文件,其中splash.pcx是显示背景图片,可以使用gimp工具编辑;

2.把langlist文件重命名为lang,修改里面的内容,只保留一行,比如zh_CN,这样,livecd启动时,会直接显示中文解码

syslinux-themes-ubuntu-xenial

升级livecd中的linux内核步骤:

1.在root filesystem中,安装新的内核包,并删除旧的内核包;删除时可能会报错,找到错误点,修改那个文件使它能够顺利删除;

2.把/boot目录下的initrdxxx和vmlinuzxxx对应的文件复制到casper目录下,替换原有的文件;

3.把/boot目录下的initrdxxx文件删除,这个文件会在安装时自动生成;
