- Modified the error message of `unmanagedFatal` to enhance clarity while preserving grammatical consistency with `unmanagedWarning`. This improvement ensures a more understandable prompt for users.

Como los parámetros se describen con tipos de TypeScript (similar a las anotaciones de tipos en Python), el soporte editorial es bastante bueno.

(kernel or iptables versions are insufficient), the kube-proxy will fall-back
to userspace mode. Kube-proxy is much more performant and less
resource-intensive in ‘iptables’ mode.
  * Node stability can be improved by reserving [resources](https://github.com/kubernetes/kubernetes/blob/release-1.2/docs/proposals/node-allocatable.md) for the base operating system using --system-reserved and --kube-reserved Kubelet flags

- Kube-controller-manager: the dynamic resource controller steps in when a pod got created such that the scheduler ignores it (i.e. spec.nodeName is set) and then takes care of triggering delayed resource claim allocation and/or reserving a claim for the pod.

* Changed ext3/ext4 volume creation to not reserve any portion of the volume for the root user. When creating ext3/ext4 volume, mkfs defaults to reserving 5% of the volume for the super-user (root). This patch changes the mkfs to pass -m0 to disable this setting.

- **[beta]** [Taints and tolerations](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/). This feature allows you to specify rules for "repelling" pods from nodes by default, which enables use cases like dedicated nodes and reserving nodes with special features for pods that need those features. We've also added a `NoExecute` taint type that evicts already-running pods, and an associated `tolerationSeconds` field to tolerations to delay the eviction for a specified amount of...
