Decompress the cpio image:
gzip -d /boot/initrd-2.6.23.13-grsec-sg1.cpio.gz
Create a directory where you want to extract the initrd:
mkdir /root/initrd
Extract the files from the cpio image:
cd /root/initrd
cpio -idvm < /boot/initrd-2.6.23.13-grsec-sg1.cpio.gz

== Create the new initrd ==
cd /root/initrd
find .|cpio -o -Hnewc > /boot/initrd-2.6.23.13-grsec-sg2.cpio
gzip /boot/initrd-2.6.23.13-grsec-sg2.cpio
mv /boot/initrd-2.6.23.13-grsec-sg2.cpio.gz /boot/initrd-2.6.23.13-grsec-sg2.img
