Currently buzgilla only allows a single default owner per component. For example, the kernel can have only 1 default owner. This is problematic because we have different kernel maintainers for different releases. ie jparadis - RHEL2.1, petrides - RHEL3, jbaron - RHEL4, davej - Fedora. So what we need is the ability to have a different default owner per release tag associated with the component. (per Tim Burke)
The Content Definition Workflow project was the initiative taken to address the majority of the support/engineering workflow issues. As that project has completed I am closing this set of bugs. If there are any remaining items not addressed please escalate to Marco Bill-Peter.
