Hi,

i want to add some modules and scripts to my initrd. At first I have decompressed the initrd with bzip2. Then I want to mount ("mount -o loop ./initrd /mnt/initrd"), but I get the Message that the Filesystem is missing and ext2 and ext3 don't work?

What I have done wrong ???

thx

Nowadays, the initrd image is a compressed cpio archive (unpack with bzip2 -dc initrd | cpio -i . Careful: this command unpacks into current directory)

Later, you can recompress the modified image with:

find . -print | cpio -c -o | bzip2 -c >../initrd

(Again, this command should be run from within the initrd's root directory)

Or just use the --merge option with the makeImage utility to add any additional files that you may need.
