Since commit2df8220cc5("kbuild: build init/built-in.a just once"), the .version file is not touched at all when KBUILD_BUILD_VERSION is given. If KBUILD_BUILD_VERSION is specified and the .version file is missing (for example right after 'make mrproper'), "No such file or director" is shown. Even if the .version exists, it is irrelevant to the version of the current build. $ make -j$(nproc) KBUILD_BUILD_VERSION=100 mrproper defconfig all [ snip ] BUILD arch/x86/boot/bzImage cat: .version: No such file or directory Kernel: arch/x86/boot/bzImage is ready (#) Show KBUILD_BUILD_VERSION if it is given.

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.
