The mountpoint is `/var/run/secrets/kubernetes.io/serviceaccount`. Something about the way that Cloudify Manager is started (possibly because `/sbin/init` is run) causes this mountpoint to be hidden. `setup-secret.sh` will recreated the directory if it's not present and symbolically link it to a copy of the credentials mounted at `/secret` in the container file system.
