In version 1.32.1-gke.1729000 and later, you can customize specific kubelet and Linux kernel parameters like sysctls and huge pages by using the nodeSystemConfig field in your GKE compute classes

## Feature In version 1.32.1-gke.1729000 and later, you can customize specific kubelet and Linux kernel parameters like sysctls and huge pages by using the [nodeSystemConfig](https://cloud.google.com/kubernetes-engine/docs/concepts/about-custom-compute-classes#customize-node-system-config) field in your GKE compute classes. Additionally, you can now specify default values for fields that are omitted in individual rules in a compute class by using the [priorityDefaults](https://cloud.google.com/kubernetes-engine/docs/reference/crds/computeclass#priorityDefaults) field. For details, see [About custom compute classes](https://cloud.google.com/kubernetes-engine/docs/concepts/about-custom-compute-classes#autoprovisioning-and-compute-classes).
