## How to update the Linux kernel?

If you don't care about educational patches:

    cd linux
    git fetch
    git checkout master

If you do:

    last_mainline_revision=v4.14
    git rebase --onto master $last_mainline_revision

Then rebuild the kernel:

    ./build -t linux-reconfigure

Now, all you kernel modules may break, although they are usually trivial breaks of things moving around headers or to sub-structs.

The userland, however, should simply not break, as Linus enforces strict backwards compatibility of userland interfaces.

This backwards compatibility is just awesome, it makes getting and running the latest master painless.

This also makes this repo the perfect setup to develop the Linux kernel.

## How to add new Buildroot options?

    cd buildroot/output.x86_64~
    make menuconfig

Hit `/` and search for the settings.

Save and quit.

    diff .config.olg .config

Copy and paste the diff additions to `buildroot_config_fragment`.
