TIL: Save your kernel config after customizing with 'make savedefconfig'. This creates a minimal defconfig from your full .config, making it portable and version-controllable. Much cleaner than committing the full 10K line .config file.


```bash
# After running make menuconfig
make savedefconfig
mv defconfig arch/arm64/configs/my_device_defconfig

# Later, restore with:
make my_device_defconfig
```
