+module: selinux_permissive
+short_description: Change permissive domain in SELinux policy
+description:
+  - Add and remove domain from the list of permissive domain.
+version_added: "1.9"
+options:
+  domain:
+    description:
+        - "the domain that will be added or removed from the list of permissive domains"
+    required: true
+  permissive:
+    description:
+        - "indicate if the domain should or should not be set as permissive"
+    required: true
+    choices: [ 'True', 'False' ]
+  no_reload:
+    description:
+        - "automatically reload the policy after a change"
+        - "default is set to 'false' as that's what most people would want after changing one domain"
+        - "Note that this doesn't work on older version of the library (example EL 6), the module will silently ignore it in this case"
+    required: false
+    default: False
+    choices: [ 'True', 'False' ]
+  store:
+    description:
+      - "name of the SELinux policy store to use"
+    required: false
+    default: null
+notes:
+    - Requires a version of SELinux recent enough ( ie EL 6 or newer )
+requirements: [ policycoreutils-python ]
