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. ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

If you want *ALL* modules, just copy the centos-default config to .config If you want everything from your custom config, copy *that* to .config If you want to mix-and-match, you're probably going to end up running diffconfig in one window, and 'make menuconfig' in another, and for each thing that's different, decide if you want it included or not. Oh, and copy the config that's closest to what you want to .config to minimize the number of changes you'll need to do. pgppe0oISE0tk.pgp Description: PGP signature ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
Update a newly-created '.config' file with some predefined values
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.
