Grub2 will be used on machines that have no UEFI boot, that is. most less-than-current hardware.
It is *not* dead, it is just that grub will not be used when a dramatically simple solution like gummiboot is available.
"Gummiboot is an open source boot loader for systems using the Unified Extensible Firmware Interface. Developed by the Red Hat employees Kay Sievers and Harald Hoyer, it is intended to be a minimal alternative to GNU GRUB that "just works"—it automatically detects bootable images (including Linux kernel images, operating systems, and other boot loaders), does not require a configuration file, provides a basic menu interface, and can also integrate with systemd to provide performance data."[1]
If it "just works", detects bootable images and does not require a configuration file then why need grub2 and all of its plethora of convoluted cfg etc files?
If we have rEFInd why bother to have gummiboot? rEFInd even comes with a nicer menu, http://www.rodsbooks.com/refind/ Both all should fall to the category of "(Muit-)Boot Manager" not "Boot loader". They all work by chainloading other efi images, like grub.efi, elilo.efi which performs the real booting task. And if your linux kernel has efi stub, it can also boot by gummiboot, but you have to realize that in this case gummiboot is not booting the kernel at all, but the boot code in the efi stub. Remember that UEFI firmware also comes with boot manager and they offered similar capabilities, the major difference is that gummiboot/rEFInd provide more friendly way for dealing with mulitiboot under linux. That is also say that UEFI firmware boot manager can boot linux kernel with efi stub. It's not bootloader in real, unless you can ask it to boot a plain bzImage kernel in a plain linux partition with plain ext3 file system. Regards, Michael
