啟動部分的菜單,顯示內容等是在gfxboot-theme-ubuntu源碼中,
apt source gfxboot-theme-ubuntu gfxboot
cd gfxboot-theme-ubuntu*/
make DEFAULT_LANG=zh_CN
sudo cp -af boot/* ../live-cd/isolinux/
參考:
https://help.ubuntu.com/community/LiveCDCustomization
如果是單純的不顯示語言選擇窗口則可以通過修改配置文件來解決:
1.解壓isolinux中的bootlogo文件,其中splash.pcx是顯示背景圖片,可以使用gimp工具編輯;
2.把langlist文件重命名為lang,修改裡面的內容,只保留一行,比如zh_CN,這樣,livecd啟動時,會直接顯示中文解碼
syslinux-themes-ubuntu-xenial
升級livecd中的linux內核步驟:
1.在root filesystem中,安裝新的內核包,並刪除舊的內核包;刪除時可能會報錯,找到錯誤點,修改那個文件使它能夠順利刪除;
2.把/boot目錄下的initrdxxx和vmlinuzxxx對應的文件復制到casper目錄下,替換原有的文件;
3.把/boot目錄下的initrdxxx文件刪除,這個文件會在安裝時自動生成;
