+The cpio file format used by initramfs is the "newc" (aka "cpio -H newc")
format, and is documented in the file "buffer-format.txt". There are
two ways to add an early userspace image: specify an existing cpio
archive to be used as the image or have the kernel build process build
CONFIG_INITRAMFS_SOURCE. Sources can be either directories or files -
cpio archives are *not* allowed when building from sources.

specified directory name will be mapped to '/'. When packaging a
directory, limited user and group ID translation can be performed.

The standalone klibc distribution currently provides three components,
in addition to the klibc library:
initrd format, an cpio archive. It must be called "/init". This binary
is responsible to do all the things prepare_namespace() would do.

+ To maintain backwards compatibility, the /init binary will only run if it
comes via an initramfs cpio archive. If this is not the case,
init/main.c:init() will run prepare_namespace() to mount the final root
and exec one of the predefined init binaries.
