How to Cleanup Boot Menu By Removing Old Kernels?
The Linux kernel is the core component of the Linux operating system. It acts as a bridge between the hardware and software layers, providing an interface for programs to interact with the underlying hardware.
The kernel is responsible for managing system resources, such as memory, processors, and devices, and provides essential services like process scheduling, file system management, and device drivers.
It is also responsible for coordinating and executing system calls, ensuring security and stability, and enabling the efficient operation of any Linux-based system.
Kernel updates, also known as kernel upgrades or kernel patches, refer to the process of updating the Linux kernel to a newer version or applying patches to fix bugs, improve performance, enhance security, or add new features.
Typically, most Linux distributions will keep the current kernel version and at least one older one in case of rollback. However, you may encounter scenarios where you have more than one older kernel version available in your boot entry.
This can lead to disk usage or a cluttered boot menu. In this tutorial, we will learn the various steps you can use to remove old kernel versions from your system.
