Note that the Kickstart manual specificially says:
-- ---- ---- ---- --- CUT HERE -- ---- ---- ---- ---- ---- ---- ----
For kickstart upgrades, the following items are required:
* Language
* Language support
* Installation method
* Device specification (if device is needed to perform
installation)
* Keyboard setup
* The upgrade keyword
* Boot loader configuration
If any other items are specified for an upgrade, those items will be
ignored (note that this includes package selection).

So you're out of luck running %pre or %post stuff during upgrades. The
theory is that the items have already been installed and configured, and
the upgrade is primarily to update the code--not the configs. That's
also why the package selection code is also disabled during upgrades...
you can only upgrade things already installed. Dependencies are handled
if a new version of something requires another RPM, but you can't
_install_ new or additional packages.
If you must run stuff after the upgrade but before the system is fully
up, you'll have to boot in single-user mode and do your thing there.
Sorry!
