Introduction


For all Linux distributions, including Ubuntu, CentOS, and Fedora, a kernel is vital. It is by default installed for most Linux versions when the OS is installed, hence we generally don't have to compile the kernel. Even when there is a critical update to be installed in the kernel, it can be done using apt-get or yum on the Linux system.

However, there might be few situations where we have to compile the kernel from a source ourselves. A few of these situations are as follows:

  • Enabling experimental features in the kernel

  • Enabling new hardware support

  • Debugging the kernel

  • Exploring the kernel source code
