I ran into an issue when trying to get this to work with a NFS server which I did not have direct control over (EFS). As part of the PersistentVolumeClaim, there is no easy way to set the UID and GID of the created directory.on the networked FS.
My only concern with this chown is that some user out there might be running jupyterhub in an odd configuration where $NB_USER is not supposed to have these exact permissions on the storage. I think this is quite unlikely, but it is worth mentioning.
I chronicled my experiences with working around this issue and setting up z2jh on EFS in https://github.com/jupyterhub/zero-to-jupyterhub-k8s/issues/421 with @yuvipanda.
* Refactor to use sudo to become jovyna when the
container starts as root
* Retain all environment variables when becoming
jovyan
* Handle start.sh without additional commands when
launching a container as NB_USER too
