// Optional: Default to true.
  // If set to true or not present, the pod will be run in the host user namespace, useful
  // for when the pod needs a feature only available to the host user namespace, such as
  // loading a kernel module with CAP_SYS_MODULE.
  // When set to false, a new userns is created for the pod. Setting false is useful for
  // mitigating container breakout vulnerabilities even allowing users to run their

**Note**: You probably don't need `contextvars`, and you should probably avoid using them. But they are powerful and useful in some advanced scenarios, for example, migrating from code that used Flask's `g` semi-global variable.

* AWS Security Groups created for ELBs will now be tagged with the same additional tags as the ELB; that is, the tags specified by the "service.beta.kubernetes.io/aws-load-balancer-additional-resource-tags" annotation. This is useful for identifying orphaned resources. ([#58767](https://github.com/kubernetes/kubernetes/pull/58767), [@2rs2ts](https://github.com/2rs2ts))

- Kubernetes will try to acquire the iptables lock every 100 msec during 5 seconds instead of every second. This is especially useful for environments using kube-proxy in iptables mode with a high churn rate of services. ([#85771](https://github.com/kubernetes/kubernetes/pull/85771), [@aojea](https://github.com/aojea)) [SIG Network]

    * try to only update vm if detach a non-existing disk when got <200, error> after detach disk operation
* This adds some useful metrics around pending changes and last successful ([#78602](https://github.com/kubernetes/kubernetes/pull/78602), [@paulgmiller](https://github.com/paulgmiller))
    * sync time.
 

  
  kubelet also ignores an error during opening `/dev/kmsg`.
  This feature gate also allows kube-proxy to ignore an error during setting `RLIMIT_NOFILE`.
  
  This feature gate is especially useful for running Kubernetes inside Rootless Docker/Podman with `kind` or `minikube`. ([#92863](https://github.com/kubernetes/kubernetes/pull/92863), [@AkihiroSuda](https://github.com/AkihiroSuda)) [SIG Network, Node and Testing]

<p>
Current implementations provide several built-in functions useful during
bootstrapping. These functions are documented for completeness but are not
guaranteed to stay in the language. They do not return a result.
