Currently there are a handful of settings that are common across several different config files. Here are a few examples I know of:
* log level
These settings currently have to be altered in many places if users wish to change them, which could be painful especially if the user forgot one. For example, there are 3-5 places where verify_ssl has to be set to False for evaluation of Pulp. If we had a pulp.conf, these common settings could be moved there and there would only be one place that users would need to adjust them.
This is solidly in the "would be nice" category, so I marked it low severity.
