Hello everybody,
I have a host machine and I have a VM machine running CentOS 7 with 3.x. There is a kernel source tree on the host. I have made 'make menuconfig', populated all options that I want to have in my custom kernel and as a result got a '.config' file. Then I copied a centos-default distro config file from my VM's 'boot' catalog to my host's kernel source tree catalog. So now I have two files in my source tree: '.config' and '.config.old'. I am able to see difference between them using the following command:
scripts/diffconfig .config.old .config | less
But is there anyway to update values in '.config' file with the apropriate values from '.config.old' file? I just want to make sure that all modules will be included in a new custom kernel.
Thanks in advance, Roman
I have found a solution. There is a script: scripts/kconfig/merge_config.sh It allows to mix many configuration files in a base config. For example: scripts/kconfig/merge_config.sh -m -r .config ~/kernel/conf_mixins/.config_deb There are kernel options in .config_deb that include some debugging to the kernel default .config.
