+------------------

+Default: False
+
+The `snapper_states` value is used to enable taking snapper snapshots before
+and after salt state runs. This allows for state runs to be rolled back.
+
+For snapper states to function properly snapper needs to be installed and
+enabled.

+-------------------------

+Default: ``root``
+
+Snapper can execute based on a snapper configuration. The configuration
+needs to be set up before snapper can use it. The default configuration
+is ``root``, this default makes snapper run on SUSE systems using the
+default configuration set up at install time.
