For out-of-tree builds, this script invokes cpio twice to copy header files from the srctree and subsequently from the objtree. According to a comment in the script, there might be situations in which certain files already exist in the destination directory when header files are copied from the objtree: "The second CPIO can complain if files already exist which can happen with out of tree builds having stale headers in srctree. Just silence CPIO for now." GNU cpio might simply print a warning like "newer or same age version exists", but toybox cpio exits with a non-zero exit code unless the command line option "-u" is specified. To improve compatibility with toybox cpio, add the command line option "-u" to unconditionally replace existing files in the destination directory.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
