NAME

       unmkinitramfs - extract content from an initramfs image

SYNOPSIS

       unmkinitramfs [options] <initramfsfile> <directory>

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.
