users/init.sls

     {% if not user.get('createhome', True) %}
     - createhome: False
     {% endif %}
-    {% if user.get('remove_groups', True) %}
-    - remove_groups: True
-    {% else %}
-    - remove_groups: False
-    {% endif %}
+    - remove_groups: {{ user.get('remove_groups', 'False') }}
     - groups:
       - {{ user_group }}
       {% for group in user.get('groups', []) -%}
