The following should give you some ideas:
# mount -r -t cramfs /boot/initrd.img-2.6.8-11-amd64-k8 /mnt -o loop=/dev/loop1
# df /mnt
Filesystem 1K-blocks Used Available Use% Mounted on
10940 10940 0 100% /mnt
# ls -l /boot/initrd.img-2.6.8-11-amd64-k8
-rw-r--r-- 1 root root 4182016 Oct 1 14:21 /boot/initrd.img-2.6.8-11-amd64-k8
I got the information from mount(8), and you may want to look at the
-x option in cramfsck(8) (in the cramfsprogs package). I am sure
there are other ways to do this.
