* Provisioner Daemon PSKs are no longer recommended for use with external
provisioners. Consider migrating to scoped provisioner keys instead. For more
information, see: https://coder.com/docs/admin/provisioners#authentication

Is it ever sensible to accept both? I think we can only accept one or other as the authentication credential

Yep, you're correct:

error: cannot provide both provisioner key --key and pre-shared key --psk

I can remove this test and add a check in the Helm chart, but I'd worry about logic drift.

The key name is currently hard-coded in_coder.tpl:

- name: CODER_PROVISIONER_DAEMON_PSK  valueFrom:    secretKeyRef:      name: {{ .Values.provisionerDaemon.pskSecretName | quote }}      key: psk{{- if include "provisioner.tags" . }}

This wasn't changed as part of this PR. I can add a separate PR to allow customizing the key name, if required.
