Code review comment for lp:~xnox/debian-cd/ubuntu-fwsetup

ok, I was -1 on the idea of using fwsetup as a replacement for the "Boot next device" option, but I can see that the rationale for having this on installed systems also applies equally well to live images (even though in practice it would be unusual for a system to both be configured with UEFI fastboot and have the live image as the first boot option that you can't remove). So I'm +1 on adding both of these.
