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 im-
age 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, ex-
cept where an early (uncompressed) initramfs with system firmware is
prepended to the regular compressed initramfs.
