Linux内核升级之制作initrd.img及其new-kernel-pkg(.sh)使用

1、从编译好的源码中拷贝bzImage和System.map文件到/boot目录，并重命名。

# cp linux-2.6.32.6/arch/i386/boot/bzImage /boot/vmlinuz-2.6.32.6

# cp linux-2.6.32.6/System.map /boot/System.map-2.6.32.6

 

注意：

1)、vmlinuz和System.map的全名(包括版本号)一定要正确，要不new-kernel-pkg的脚本无法找到上述文件！

2)、编译过程中执行：make bzImage, make modules, make modules_install(拷贝*.ko文件到/lib/modules/2.6.32.6目录下)

 

2、执行命令制作initrd-2.6.32.6.img

# new-kernel-pkg --mkinitrd --depmod --install 2.6.32.6

 

3、/boot目录文件

 

4、new-kernel-pkg脚本

 

 

#!/bin/bash

#

# new-kernel-pkg

# Invoked upon installation or removal of a kernel package, the following

# tasks are/can be done here:

# creation/removal of initrd

# run of depmod/removal of depmod generated files

# addition/removal of kernel images from grub/lilo configuration (via grubby)
