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.
