怎么查看 initrd 呢？

macfanscndl

首先祝贺大家国庆节快乐

我使用的是默认的安装，在／boot 下面能看到一个 initrd 的文件，但是应该怎么查看它呢？
P.S.
   我尝试过把它加上.gz然后解压，最后还是失败了。

糊涂

这是个二进制文件吧。你看它作甚？

无心徘徊

不是二进制文件 ， 用CPIO这个命令！！ 2.6内核后， 已经换了文件的制作方式了！

zcat ../initrd-2.6.25.16-0.1-pae | cpio -i

这个是正解但是输出的有一点奇怪

zcat ../initrd-2.6.25.16-0.1-pae | cpio -i
如果是root下用， 恐怕死路一条。
zcat ../initrd-2.6.25.16-0.1-pae | cpio -i --no-absolute-filenames

find . | cpio --quiet -H newc -o | gzip -9 -n > /boot/imagefile.img

楼上的是正解，内核2.6以后initrd由cpio来制作。

mkdir ~/initimage
cd !$
zcat ../initrd-2.6.25.16-0.1-pae | cpio -i --no-absolute-filenames   
//首先解压文件然后，复制到当前的文件夹 --no-absolute-filenames 是忽略绝对路径
//然后复制到印象
find . | cpio --quiet -H newc -o | gzip -9 -n > /boot/imagefile.img
//最后查看一下
ls -l |grep imagefile
