本文主要是介绍Linux内核升级之制作initrd.img及其new-kernel-pkg(.sh)使用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
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)
