009.04.91.3. With the evolution of boot loaders from LILO to GRUB and now GRUB2, what specific improvements have been made in terms of functionality and compatibility, particularly in accommodating modern computing architectures like UEFI, and how has this impacted the user experience and system management for Linux users?
Starting with LILO, it had certain limitations like it lacked support for dynamically allocated kernels and configurations outside the MBR. GRUB resolved this issue to a certain extent. GRUB2, an iteration to the original GRUB brought much more features and flexibility, supporting scripts, and a better UI, enhanced module management. With GRUB2, users not only start the operating system but also provide essential capabilities for system management, recovery and configuration.
