SYNOPSIS¶
unmkinitramfs [options] <initramfsfile>

using cpio. If the image contains multiple segments, each are passed to
cpio in order.
OPTIONS¶
- -h

- -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.
