In this file one can add options with which to build CRIU. Each line is (for now) expanded into CONFIG_$(TEXT) macros defined in config.h that can be tested later in the code. v2: Add .config to .gitignore v3: Don't check that make mrproper removes .config https://github.com/xemul/criu/issues/235 travis-ci: success for Don't compile in binfmt_misc dumping code by default (rev3) Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com> Reviewed-by: Dmirty Safonov <dsafonov@virtuozzo.com>
