NAME
       unmkinitramfs - extract content from an initramfs image
SYNOPSIS
       unmkinitramfs [-v] initramfs-file directory
       unmkinitramfs -h
DESCRIPTION
       The  unmkinitramfs  command  extracts  the  content  of a given initramfs image using cpio.  If the image
       contains multiple segments, each are passed to cpio in order.
OPTIONS
       -h     Display usage information and exit.
       -v     Display verbose messages about extraction.
USAGE EXAMPLES
       Extract initramfs content of current running kernel:
       unmkinitramfs /boot/initrd.img-$(uname -r) initramfs/
BUGS
       unmkinitramfs cannot deal with multiple-segmented initramfs images, except where an early  (uncompressed)
       initramfs with system firmware is prepended to the regular compressed initramfs.
