Bootparameter

Boot parameters, also known as kernel parameters, are a set of options passed to the operating system's kernel during the boot process. These parameters allow for customization and control over how the kernel initializes and behaves. They are typically configured by the bootloader, such as GRUB or systemd-boot, and can be edited manually before the system starts.

Common uses for boot parameters include specifying the root filesystem device, enabling debugging modes, configuring hardware parameters, and selecting different operating system modes. For example, a parameter like "root=/dev/sda1" tells the kernel where to find the main file system. Other parameters can be used to disable certain hardware components or to load specific drivers.

In Linux-based systems, boot parameters are often a powerful tool for system administrators and advanced users. They can be used to troubleshoot boot issues, optimize system performance, or experiment with different kernel configurations. The exact set of available boot parameters varies depending on the operating system and the kernel version. Many distributions provide documentation detailing the commonly used and available parameters. Modifying boot parameters incorrectly can prevent the system from booting, so caution is advised when making changes.
