The 'defconfig_list' is a weird attribute. If the '.config' is missing, conf_read_simple() iterates over all visible defaults, then it uses the first one for which fopen() succeeds. config DEFCONFIG_LIST string depends on !UML option defconfig_list default "/lib/modules/$UNAME_RELEASE/.config" default "/etc/kernel-config" default "/boot/config-$UNAME_RELEASE" default "$ARCH_DEFCONFIG" default "arch/$ARCH/defconfig" However, like other symbols, the first visible default is always written out to the .config file. This might be different from what has been actually used. For example, on my machine, the third one "/boot/config-$UNAME_RELEASE" is opened, like follows: $ rm .config $ make oldconfig 2>/dev/null scripts/kconfig/conf --oldconfig Kconfig # # using defaults found in /boot/config-4.4.0-112-generic # * * Restart config... * * * IRQ subsystem * Expose irq internals in debugfs (GENERIC_IRQ_DEBUGFS) [N/y/?] (NEW) However, the resulted .config file contains the first one since it is visible: $ grep CONFIG_DEFCONFIG_LIST .config CONFIG_DEFCONFIG_LIST="/lib/modules/$UNAME_RELEASE/.config" In order to stop confusing people, prevent this CONFIG option from being written to the .config file.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
