#make dep 建立编译时需要的从属文 件，没有编译过的代码可以跳过
#make clean 这里也可以跳过
#make
漫长的等待中...
#make modules (编译模块)
#make modules_install
#make install(安装内核)
[root@localhost linux-2.6.37.2]# make install
sh /usr/src/kernels/linux-2.6.37.2/arch/x86/boot/install.sh 2.6.37.2 arch/x86/boot/bzImage \
System.map "/boot"
4.把新镜像文件放到tmp中
# cp /boot/initrd-2.6.37.2.img /tmp
在tmp中新建一个文件夹
# mkdir /tmp/newinitrd
# cd /tmp/newinitrd
然后解压initrd-2.6.37.2.img到newinitrd文件夹
[root@localhost newinitrd]# zcat ../initrd-2.6.37.2.img | cpio -i
11260 blocks
[root@localhost newinitrd]# ls
bin dev etc init lib proc sbin sys sysroot
用vim修改init文件
其中：
echo "Loading dm-region-hash.ko module"
insmod /lib/dm-region-hash.ko
echo "Loading dm-region-hash.ko module"
insmod /lib/dm-region-hash.ko
删去重复的两行，不然启动会echo这个错误！
重新打包镜像
[root@localhost newinitrd]# find . | cpio -c -o > ../initrd-2.6.37.2_new.img
11260 blocks
然后把新的镜像文件移动到/boot
[root@localhost newinitrd]# mv ../initrd-2.6.37.2_new.img /boot
修改/boot/grub/grub.conf
#boot=/dev/sda
default=1 #改为0
timeout=15
splashimage=(hd0,7)/grub/splash.xpm.gz

5.重新启动
