Comment # 15 on bug 1223167 from Stefan Hundhammer

So, this whole products thing is a lot of smoke and mirrors; it's mostly
metadata, injected into the system by a -release package for each product. The
-release package have RPM 'provides' dependencies to provide symbols of the
'product() = PRODUCT_NAME' type that are added as a new type of object into the
RPM database.

As you can see, I used the same ISO file as you, and actually the data look
quite consistent. Yet, something must be missing; but what?
