This seems like a reasonable step, but outside some special cases it's 
not going to be terribly useful - general purpose EFI machines aren't 
going to boot unless you can set the boot variable, which requires 
runtime services. ChromeOS machines presumably have their own way of 
handling this so I've no objection to adding it if it helps them, but 
just wanted to make sure people knew that it's something that we'd still 
need to fix up if we want this to work elsewhere.
