内核配置文件 .config:

运行 "make LANG=zh_CN.GB18030 LC_ALL= menuconfig" 调出配置菜单后, 全部使用的是默认选项, 然后保存生成了 .config 文件. 由于贴子字数的限制, 没有贴出 .config 的内容, 请见谅.

Answer 2

lfs默认没有生成initrd.img,所以你应该在编译内核时把硬盘文件系统的驱动编译进内核，而不是编译成模块方式，编译成模块方式后，就会在生成initrd.img时被包含进去，也需要修改引导方式为

 linux  /boot/vmlinuz..... root=/dev/sdb1 
 initrd /boot/initrd.img.....  

我是在真机上做LFS6.6， 我是直接把硬盘文件系统的驱动（我的是ext3)直接编译进内核， 可以直接用

linux /boot/vmlinuz....  root=/dev/sdb1 

来引导系统，跳过使用 initrd /boot/initrd.img......

网上也有和你一样情况的http://bbs.chinaunix.net/thread-35679...
