Code:

gunzip < /boot/initrd.img | cpio -i --make-directories

Hi all. This is my first post on this forum.

I tryed to extract the initrd.img on my FC6 with the command

Code:

gunzip < /boot/initrd.img | cpio -i --make-directories

now I'd like to edit the init file and then create again the initrd.img. How to create again initrd.img?

Thanks a lot !

hi tonyda,

Welcome to the LinuxForums.

Code:

find ./ | cpio -H newc -o > initrd.cpio
gzip initrd.cpio
mv initrd.cpio.gz initrd.img
