Instead of doing this, which is getting harder and harder to achieve while still keeping functionality intact, using the ability to chain cloop files can be very useful. I think that the main reason it has not been exploited more, is that it is kind of "third level" extension: First, the persistent store caters for most needs, second, creating a new primary cloop image suffices for most of the rest. I'm rather doubtful as to the usefulness of implementing version upgrades this way. Even within one release, it quickly becomes an hassle to keep it upgraded, and I guess this will be even worse across versions.
I would not refute that DVD 4GB limit is the core essense here, but
1. How many users/percentage who have downloaded, say 6.7 and regularly use it from DVD? Or is DVD version become more a storage/distribution media?
2. What percentage of users would want to have distributable version of cloop file for VMware Workstation and Oracle XE (I mean if it free from license hassles)? I would!!
3. Would I be downloading updatedable cloop for 6.7 even if its 1GB in size, rather than 4 GB DVD?

If one uses Knoppix on several systems (USB), he would likely use an update method.
I am more keen on various addon cloop modules that can be build apart from regular DVD.
