+# Concept for tracking changes
+- Create new commit (if possible)
+- If force is unset: Diff system's files against current state by copying them into the current state branch
+- Then, diff the package state against the state branch by dumping it
+- Else, or if no diff, continue
+- Copy normal config files into correct directories
+- Render and copy renderables
+- Retrieve explicitly installed packages and remove those that are not present in goal and install those that are not present in current state
