I tried to submit an enhancement request (severity: enhancement) to add a new package to powertools. I was forced to choose a component that already exists in the list in order to submit the request. I had to choose an invalid component (9wm) to suggest the package ttywatch. Enhancement requests should not necessarily require known component.
On the other hand: bugzilla must know who to assign the thing. It's a good policy to file this kind of requests to the nearest matching package as he's likely to be in position to decide about the addition.
It is a design issue with Bugzilla that it requires a component to be selected so as to know who to assign it to. One idea would be to create a "no_component" component for each product and have a default owner for those type of requests/bugs. I am changing to assigned RFE and will talk to someone about it when I get into work on Monday.
Please use the component 'distribution' for these type bugs.
