Ubuntu20.04(LiveCD)的initrd解压后怎么压缩回去

[WinXaaa]

我使用unmkinitramfs命令成功的解压了initrd，有什么办法能够把它再按照原来的方法压缩回去吗？

[astolia]

就用cpio，你做不成功的话，把你从unmkinitramfs开始执行的所有命令都发上来才知道哪一步做错了

[WinXaaa]

amd和intel的微码要一起打包吗？

[WinXaaa]

有什么办法可以把initrd文件的大小控制在原版的大小（80MB）左右吗？

如果不在乎cpu的漏洞/缺陷，可以不打包。

有什么办法可以把initrd文件的大小控制在原版的大小（80MB）左右吗？

自己去看/etc/initramfs-tools/initramfs.conf里面用的COMPRESS是什么，然后用那个压缩程序压缩就是

我使用cpio进行压缩，在光盘的启动过程中，提示init有错误无法启动
下面是错误信息：

[astolia]

就用cpio，你做不成功的话，把你从unmkinitramfs开始执行的所有命令都发上来才知道哪一步做错了

从错误信息来看，是你打包时的路径没弄对

[WinXaaa]

我执行的所有命令：
unmkinitramfs initrd initrdfile #解压initrd
删除了微码文件（intel，amd）
cd main #进入内核文件夹
find . | cpio -o -H newc > ../initrd #使用cpio的newc格式打包
#获得initrd

请问有什么地方做错了吗？

[astolia]

命令看起来没错。但还是很奇怪，livecd里的initrd里面，根本就没有/sbin/init或/bin/init，但上面的错误提示里却写着exists。
你把生成的initrd文件用以下命令列出内容，发上来我看看

代码： 全选

cpio -tv < initrd  | grep -E 'init|bin' | grep -v firmware

这是在虚拟机里打包的（命令也是在虚拟机里执行的）

[astolia]

你这里面也没见着有/sbin/init这些啊。要不你把你重做的iso传到哪个网盘里我下载来看看

明明能压缩到1/5大小，你就压缩一下再上传嘛，搞得你上传也费事，我下载也费事

我明白是怎么回事了。你肯定觉得win下修改起来方便点，就在虚拟机里挂载了个win共享文件夹，把initrd的内容直接解包到那里面去了。
win分区的文件系统又不支持linux下面的文件权限和其他一些特性，你这么一搞，不仅文件权限乱了，更重要的是所有的软链接也被破坏了，原先的到目录的软链接都成了空文件，怪不得会报-20错误

[WinXaaa]

。。。
我知道了，感谢你的回复
我今晚装个20.04实体机，在那里面搞吧。

[astolia]

你直接解包到虚拟机里的硬盘上嘛，只把需要改的文件拿到win下面就是了
