With CONFIG_LOCALVERSION_AUTO=y enabled, 'uname' provides much more useful output on debug kernels: Before: # CONFIG_LOCALVERSION_AUTO is not set $ uname -a Linux localhost 5.16.0-rc7+ #4563 SMP PREEMPT Thu Dec 30 08:28:38 CET 2021 x86_64 GNU/Linux After: # CONFIG_LOCALVERSION_AUTO=y $ uname -a Linux localhost 5.16.0-rc7-02294-g5537f9709b16 #4562 SMP PREEMPT Thu Dec 30 08:27:17 CET 2021 x86_64 GNU/Linux This is particularly valuable during bisection, if we want to double check the exact kernel version we are testing. (Just remove the config line, the global Kconfig default for this is default-y.)

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.
