Comment 3 for bug 1633460

The sizes reported on the web index are given in GiB, not in GB. The '4.5G' is therefore correct.

I can confirm that the images are oversized for writing to a DVD, as the standard DVD size limit is 4700372992 and the images you reference are of sizes 4783419392 and 4819716096.

It doesn't appear that there is any logic in the publisher to ensure these images fit on a DVD when published (and any logic in the image builder is off). This would probably be a reasonable thing to enforce; considering that we are creating multiple images, it seems that we would want the individual images to fit on a DVD.

We would not change this retroactively for the images that have already been released (up to and including bionic), but we should be able to fix this going forward.
