hi, is there a convenient way of creating a volume using the contents of an OCI image as the initial state i know k8s supports image volumes but that isnt quite what i want, i just want to set the initial state but then have a normal volume i have done stuff in the past with an init container which run cp/rsync etc but that doesnt quite do what i want either (i dont want restarts or multiple instances of the pod to re-copy everything - i know there are ways i could check that with bash script that only copies when the volume is empty but i am wondering if there is something nicer)
