How to see what's inside your gziped CPIO'd initrd image

Copy the initrd to somewhere else, say /tmp:


mv initrd.img to initrd.gz
*the mv to .gz is needed otherwise gunzip won't work/it will refuse to operate without the correct .gz extension


gunzip initrd.gz
cat initrd | cpio -idmv


The last command extracts the contents of initrd to your present working directory.


For 7z .lz initrd

mkdir initrdextract && cd initrdextract && cp initrd.lz initrdextract
7z e -so initrd.lz | cpio -id
