Mounting EFS/NFS to home without root privileges

I filed an issue in the docker-stacks repo, but I’m posting as here as well in case this belongs under support. It does seem to defy categorization to some extent.

Correct me if I’m wrong, but it looks like the start.sh script requires root privileges to mount NFS.

I understand that it subsequently deescalates, however, we’re using JupyterHub to provision notebooks on K8s and we want to provide a custom image field in the options form, but there’s no way for us to guarantee deescalation in that context, which is a show-stopper.

Is it possible to mount an EFS volume to the home directory without running the container as root? Has anyone successfully implemented a workaround for this configuration expectation?
