It sounds like you might have solved your problem.
If not, the following might help.
Your English is causing me some trouble in understanding what you want to do.
I _think_ you might be trying to modify the init file which is
embedded inside the initrd.gz.
This file is not a "binary" but is an "executable script".
You need to do a 3 step process
1) unpack the initrd.gz
2) edit the init file
3) repack with the modified init file
Following is from some old notes from a long time ago:
I have used (not recently) this prescription and it works.
8. Modifying an Existing Initial Ram Disk
8.1 Introduction
This section
briefly describes how an initrd_usb.gz file may be unscrambled, modified and
put back together again.
8.2 Detailed Instructions
8.2.1 Unpacking
cd go to root's home dir
mkdir clean; cd clean make and go somewhere clean
cp /boot/initrd_usb.gz . cp initrd_usb.gz to clean dir
gunzip -c initrd_usb.gz | cpio -i gunzip and expand
This unpacks a complete directory structure
- the vital file is init, edit as required.
8.2.2 Repacking
Remember to move the original file first or it will be incorporated
in the new initrd image!!
mv initrd_usb.gz ~
find . | cpio -c -o | gzip -9 > ~/initrd_usb_modified.gz
The file can then be relocated to /boot and grub.conf modified to match.
I hope this helps
