Steps to Configure Kernel

• The Linux kernel source code comes with the default configuration.

• However, you can adjust it to your needs. To do so, follow the steps below:

$ cd linux-6.0.7

• Copy the existing Linux config file using the cp command:

linux-6.0.7$ cp -v /boot/config-$(uname -r) .config
"/boot/config-6.5.0-18-generic" -> ".config"

• To make changes to the configuration file, run the make command:

$ make menuconfig

• The command launches several scripts that open the configuration menu:

linux-6.0.7$ make menuconfig
