Bootc node when created is in Staged and not in Booted desiredState

[alicefr]

During today's meeting we had the question, why the bootcnode when created is in Staged and not in Booted desired stage

 k get bootcnode -oyaml
apiVersion: v1
items:
- apiVersion: node.bootc.dev/v1alpha1
  kind: BootcNode
  metadata:
    creationTimestamp: "2026-07-06T14:23:27Z"
    generation: 1
    name: worker
    ownerReferences:
    - apiVersion: node.bootc.dev/v1alpha1
      blockOwnerDeletion: true
      controller: true
      kind: BootcNodePool
      name: workers
      uid: e611aec3-f8a4-47b7-8eeb-99cd78eed0b4

    uid: c538a582-8ca4-42cf-8036-670488ceb1f5
  spec:

How to reproduce

Create a cluster bink with a worker node and apply this yaml:

apiVersion: node.bootc.dev/v1alpha1
kind: BootcNodePool
metadata:
  name: workers
spec:
  nodeSelector:
    matchLabels:
      node-role.kubernetes.io/worker: ""
  image:
    ref: registry.cluster.local:5000/node:latest
