Bcp /boot/initramfs /tmp/initramfs.gz; gunzip /tmp/initramfs.gz; mkdir /tmp/initramfs.dir ; cd /tmp/initramfs.dir ; cpio -i < /tmp/initramfs

Ccp /boot/initramfs /tmp/initramfs.gz; gunzip /tmp/initramfs.gz; mount /tmp/initramfs /mnt/ -o loop -t initramfs

Dcp /boot/initramfs /tmp/initramfs.gz; gunzip /tmp/initramfs.gz; mkdir /tmp/initramfs.dir ; cd /tmp/initramfs.dir ; cpio -e /tmp/initramfs

Ecp /boot/initramfs /tmp/initramfs.gz; gunzip /tmp/initramfs.gz; mount /tmp/initramfs /mnt/ -o loop -t initrd

I heard the kernel likes to keep its initramfs files on a need-to-know basis. Guess we're all on a need-to-know basis today!

B) cp /boot/initramfs /tmp/initramfs.gz; gunzip /tmp/initramfs.gz; mkdir /tmp/initramfs.dir ; cd /tmp/initramfs.dir ; cpio -i < /tmp/initramfs

Wait, why are we extracting an initramfs file? Isn't that like, the kernel's private business? I hope this isn't going to be on the test!

Hold up, is this a trick question? I bet the answer is Option E, because 'initrd' is the old-school name for initramfs, right?

I've used Option C before to mount the initramfs image directly. It's a bit more straightforward than the cpio approach.

Option B looks the most comprehensive to me. Extracting the files from the initramfs image using cpio is the way to go.
