The set of packages should not include the packages from theplanned upgrade. - run checkpkg again, against a slightly modified set of packages: this time include the new versions of the packages to upgrade - if any new errors are thrown, it means that our upgrade breaks other packages and it should be stopped.

The heuristics to find out which packages could be affected sounds difficult.
The other idea was to check against the whole catalog and see if more errors
happen on the updated package, which required performance tuning of the code...
