 ### What is the behavior of Kustomize used by Flux
 
 We referred to the Kustomization CLI flags here, so that you can replicate the same behavior using the CLI. The behavior of Kustomize used by the controller is currently configured as following:
-  - `--allow_id_changes` is set to false, so it does not change any resource IDs.
-  - `--enable_kyaml` is disabled by default, so it currently used `k8sdeps` to process YAMLs.
-  - `--enable_alpha_plugins` is disabled by default, so it uses only the built-in plugins.
-  - `--load_restrictor` is set to `LoadRestrictionsNone`, so it allows loading files outside the dir containing `kustomization.yaml`.
-  - `--reorder` resources is done in the `legacy` mode, so they will be Namespaces and Cluster roles/role bindings first, CRDs before CRs, Webhooks last in the output.

+!!! hint "`kustomization.yaml` validation"
+    To validate changes before committing and/or merging, [a validation
+    utility script is available](https://github.com/fluxcd/flux2-kustomize-helm-example/blob/main/scripts/validate.sh),
+    it runs `kustomize` locally or in CI with the same set of flags as
+    the controller and validates the output using `kubeval`.
