Bootloader updater. Distribution-independent updates for bootloaders.
Today many Linux systems handle updates for bootloader data in an inconsistent and ad-hoc way. For example, on Fedora and Debian, a package manager update will update UEFI binaries in /boot/efi, but not the BIOS MBR data.
This page describes rEFInd, my fork of the rEFIt boot manager for computers based on the Extensible Firmware Interface (EFI) and Unified EFI (UEFI). Like rEFIt, rEFInd is a boot manager, meaning that it presents a menu of options to the user when the computer first starts up, as shown below. rEFInd is not a boot loader, which is a program that loads an OS kernel and hands off control to it. Many popular boot managers, such as the Grand Unified Bootloader (GRUB), are also boot loaders, which can blur the distinction in many users' minds. All EFI-capable OSes include boot loaders, so this limitation isn't a problem.
