warning on arm64 uefi cloud image

$ sudo parted ./ts.img -- print
Error: The backup GPT table is not at the end of the disk, as it should be. This might mean
that another operating system believes the disk is smaller. Fix, by moving the backup to the
end (and removing the old backup)?

vivid-server-cloudimg-arm64-uefi1.img has the same problem. and during VM kernel booting,

marked this as a duplicate of a cloud image bug.
The summary is basically that bug (the images come out with odd sizing and without partition table being updated).
the comment 1 i think is unrelated. i suspect at this point trusty images boot. if not, probably a different issue not involving cloud-utils.
