Summary
The three areas of Salt configuration that can be hooked into using the loader system are dynamic grains, external pillars, and SDB. Grains are generated on the Minion, pillars are generated on the Master, and SDB URIs can be configured in either place.
SDB modules allow configuration to be stored outside, but referenced from, the various parts of the Salt configuration. When accessed from execution modules, they are resolved on the Minion. When accessed from Salt-Cloud, they are resolved on whichever system is running Salt Cloud.
Now that we have configuration out of the way, it's time to dive into configuration management, by wrapping state modules around execution modules.
