From 37cf92135272e3892b61335725c291a8828ea2c0 Mon Sep 17 00:00:00 2001 From: Sergey Ryazanov Date: Thu, 20 Apr 2017 05:10:45 +0300 Subject: [PATCH] build: fix symlinked .config handling When running "make menuconfig" with symlinked .config (e.g. to env/.config) it renames symlink to .config.old, creates new .config file and writes updated configuration here. This breaks the desired workflow when changes in the configuration could be checked using "scripts/env diff" and commited with "scripts/env save". Since the env/.config file is not updated. Fix this issue by exporting KCONFIG_OVERWRITECONFIG=1, which forces mconf to overwrite the .config content, instead of renaming it and creating a new file. This variable is set only if .config is a symlink, otherwise the variable is not exported and the old behaviour is preserved.
