+// The Install Action is responsible for ensuring the update that's been
+// downloaded has been installed. This may be a no-op in the case of a full
+// update, since those will be downloaded directly into the destination
+// partition. However, for a delta update some work is required.
+
+// An InstallPlan struct must be passed to this action before PerformAction()
+// is called so that this action knows if it's a delta update, and if so,
+// what the paths are.
+
+// TODO(adlr): At the moment, InstallAction is synchronous. It should be
+// updated to be asynchronous at some point.
