What happened?

Trying to install k0s with OpenEBS and a default storage class per https://docs.k0sproject.io/v1.25.4+k0s.0/storage/#bundled-openebs-storage

Steps to reproduce

Create a new AWS EC2 instance, then:

$ curl -sSLf https://get.k0s.sh/ | sudo sh
$ k0s version
v1.25.4+k0s.0

$ sudo mkdir -p /etc/k0s
$ k0s config create | sudo tee /etc/k0s/k0s.yaml
$ sudo sed -e 's/type: external_storage/type: openebs_local_storage/' -i /etc/k0s/k0s.yaml
$ sudo sed -e 's/create_default_storage_class: false/create_default_storage_class: true/' -i /etc/k0s/k0s.yaml

Now k0s.yaml looks like:

apiVersion: k0s.k0sproject.io/v1beta1
kind: ClusterConfig
metadata:
  creationTimestamp: null
  name: k0s
spec:
  ...
  extensions:
    helm:
      charts: null
      repositories: null
    storage:
      create_default_storage_class: true
      type: openebs_local_storage
   ...

Then:

$ sudo /usr/local/bin/k0s install controller --single
$ sudo /usr/local/bin/k0s start

At this point kubectl get sc shows no storage class annotated as the default. I would expect that one of the storage classes would be annotated as default.

Expected behavior

Expected one of the storage classes to be the default

Actual behavior

no storage class marked as default. This actually mirrors what you show in your docs: https://docs.k0sproject.io/v1.25.4+k0s.0/storage/#bundled-openebs-storage

So without a default storage class it seems none of the following steps related to PVCs and PVs could work as documented...
