TL;DR

If you have a large PVC in k8s/k3s with selinux enabled, the volume won't mount to the pod because on boot containerd tries to assign selinux labels to all files leading to the pod never starting.

Expected behavior

Allow selinux context mounting and change the csidriver spec to announce it as described here:
