Serve an LLM with multiple GPUs in GKE is doesn't work and fails with The node was low on resource: ephemeral-storage.

- **Impacted sample:** https://github.com/GoogleCloudPlatform/kubernetes-engine-samples/blob/main/ai-ml/llm-multiple-gpus/llama3-70b/text-generation-inference.yaml
- **Impacted public tutorial:** https://cloud.google.com/kubernetes-engine/docs/tutorials/serve-multiple-gpu#autopilot
- The tutorial doesn't work end to end and the container keep on crashing with "The node was low on resource: ephemeral-storage. Threshold quantity: 10120387530, available: 9166736Ki. Container llm was using 57900024Ki, request is 0, has larger consumption of ephemeral-storage"
- Container logs is stuck at 13/30

- Somehow instead of **/data** some other mount **/etc/hosts** is getting filled and eventually runs out of disk space.

- The suspected change in the underlying GIT repo is https://github.com/GoogleCloudPlatform/kubernetes-engine-samples/pull/1495
- Using the old image `ghcr.io/huggingface/text-generation-inference:2.0.4` result in to successful run. Below is the disk usage for the same.

**NOTE:** There might be other sample also impacted with the above change. Since we don't have any automated gates for the validation.
