+Options
+-------
+
+**createiso_skip** = False
+    (*list*) -- mapping that defines which variants and arches to skip during createiso; format: [(variant_uid_regex, {arch|*: True})]
+
+.. note::
+
+    Source architecture needs to be listed explicitly.
+    Excluding '*' applies only on binary arches.
+
+
+Example

+            '*': True,
+            'src': True
