Reusing kernal customizations?

Recommended Posts

I am building from source using the vagrant process, as outlined here: https://docs.armbian.com/Developer-Guide_Using-Vagrant/

 

When running ./compile.sh, I get the option to customize the kernel via dialog and I did select some customizations. When saving the config, I choose the default `.config` as output. However, when running `./compile.sh` a second time, all the settings are back at default and I can not find any `.config` file anywhere in the tree.

 

Spoiler

No files in `userpatches` are changed since before running the compile.

 

 

Reading https://docs.armbian.com/Developer-Guide_Build-Preparation/#providing-build-configuration suggests new config files should be generated but I can't locate any. The files in userpatches are untocuhed.

 

I do see `./output/config/linux-rockchip64-current.config` - this seems to contain kernel config (I did a build for rockchip64 here). Is this what I'm looking for? If so, how do I reuse this in a sustainable way?

 

Lastly, do I get it right if by default I should put generic customizations in `./userpatches/config-default.conf` and board-specific ones in e.g. `./userpatches/rock64.conf`? (Asking since docs seem to be very out of date wrt directory structure)

Just copy linux-rockchip64-current.config after your configurations from ./output/config/ to ./userpatches/ and it will be reused for the same family (ie boards within rockchip64 family, but not rk3399)
