linux – 如何使用mkinitrd将一个模块添加到initrd

前端之家收集整理的这篇文章主要介绍了linux – 如何使用mkinitrd将一个模块添加到initrd前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我已经将 Linux(Fedora)服务器系统从IDE驱动器克隆到SATA驱动器,但是它无法启动,在交换机根目录时失败.我在目标驱动器上做了一个干净的安装,并通过检查initrd文件了解到在SATA驱动器上安装fedora时它包含了ahci模块,当我在安装工作期间没有SATA驱动器时没有使用系统.

所以我想运行mkinitrd来构建新的initrd,和旧的一样,但添加ahci模块(可能作为预加载)

我做了太多的猜测,所以我想在这里提出这个问题:
什么是从现有的initrd构建新initrd的最简单方法,只需添加一个模块?

这是两个init文件的差异

diff /media/disk/SATA_initrd/initrd/init /media/disk/PATA_initrd/initrd/init 
50a51,52
> echo "Loading crc-t10dif module"
> modprobe -q crc-t10dif
57,60d58
< echo "Loading ahci module"
< modprobe -q ahci
< echo Waiting for driver initialization.
< stabilized --hash --interval 250 /proc/scsi/scsi
66a65,68
> echo "Loading pata_amd module"
> modprobe -q pata_amd
> echo Waiting for driver initialization.
> stabilized --hash --interval 250 /proc/scsi/scsi

和我要修改的initrd的init文件.

解决方法

您无需担心所有已安装的模块.首先,启动进入救援盘.
chroot /mnt/sysimage      # this is for Fedora specifically - YMMV
cp /boot/initrd-2.26.27.24-78.2.53-fc9.x86_64.img \
     /boot/initrd-2.26.27.24-78.2.53-fc9.x86_64.old
mkinitrd --preload ahci -f /boot/initrd-2.26.27.24-78.2.53-fc9.x86_64.img \
     2.26.27.24-78.2.53-fc9.x86_64

exit and reboot the system.

华而不实的

在“驱动程序初始化”之前,您不必担心所有的modprobes

ignore  --> use the --preload *MODNAME* in the arguments to mkinitrd
ignore  --> for all the rest use --with

只需添加–preload ahci
