As Wilson pointed out, you only get the ability to make meaningful
success/failure declarations once you've performed the reboot.

I know of no firmware that will hot-patch itself when you call
UpdateCapsule(). A reboot is always required. Certainly that's the way
Windows will work from what I've read, which means that for x86 it's
pretty much set in stone.

Which means there's only so much info you can return to userspace once
you've handed the blob to the firmware. I don't see a huge problem with
printing things in kernel buffer, since that's how other
firmware-related things work today.
