SGTM, I wonder how it will act on k8s version lower than 1.33, but I think the e2e tests would tell.
On that note, can we add an e2e test ?

We will also need to fill the release-note entry.

SGTM, I wonder how it will act on k8s version lower than 1.33

i tested it with 1.32, 1.28

TaskRun.yaml

apiVersion: tekton.dev/v1
kind: TaskRun
metadata:
  name: hello-world-run-host
spec:
  taskRef:
    name: hello-worlds
  podTemplate:
    hostUsers: true

apiVersion: tekton.dev/v1
kind: TaskRun
metadata:
  name: inline-taskrun
spec:
  podTemplate:
    hostUsers: true
  taskSpec:
    steps:
      - name: say-hello
        image: alpine:3
        script: |
          echo "Hello from inline TaskSpec"

i dont see any failures in the pod

k get TaskRun
NAME             SUCCEEDED   REASON      STARTTIME   COMPLETIONTIME
inline-taskrun   True        Succeeded   28s         12s
