Having a separate simple file system for the boot loader makes a lot of
sense.  Note that vfat of EFI is the best choice, but at least it is
something.  SysV Unix from the 90s actually had a special file system just
for that, and fs/bfs/ in Linux supports that.  So this isn't really a new
thing either.
