I am sure you guys are familiar with "Overrides" in Operations Manager 2007. Since management packs are "sealed" in Operations Manager 2007, the modification of rules (for example change a threshold) is that easy. The overrides can be used to customize behavior of the Management Packs. I really like the idea but it lacks reporting capabilities. This override rule can make the configuration a big mess. I remember when we started using Group Policy, we didn't have a good tool to get the result of the GPO. I have a fear that the override rule can be very messy if you don't document everything. Hopefully, MS will come up with a reporting option to generate the "Resultant Set of Overrides".
