I'm not sure about the details, but I did notice that there's a new option
"upgrade Ubuntu" when booting from 14.04 LTS image on a machine that has
12.04 LTS. Maybe that function fills in the void?

Secondly, the new official image is already "DVD" image size wise, since
it's around 1GB while the old DVD image was 1.6GB (checked 12.04 LTS).
There is some size delta, but was it so that the old DVD image also
duplicated content because there was both the live squashfs image and deb
pool directory separately?

So it might be the new 1GB image works quite well for upgrades, at least to
a similar extent that the old DVD image did.

There'd be more use for the "old old" (until 11.04) DVD images that were
4GB+, ie something that contains more packages, but the DVD image of late
was quite close to the new "CD" image.
