IIRC in the previous version the default was the release name, like for the agent.
With the new version you don't get the credentials of the tetragon SA to access the API. An alternative approach to achieve the same is with adding automountServiceAccountToken: false to spec.template.spec of the rthooks daemonset. This may be very specific to OpenShift but the SA identity will be checked for admitting a pod using hostpath. Both the agent and the rthooks daemonset need it, which means that their respective SAs need to be bound to a convenient SCC.
The answer may be documentation but I wanted to mention this point.

API here being the k8s API server, correct? I think that's fine since rthooks does not need access to the API server. I think I'll just merge the change for now. Once/if we have a concrete problem, it would be easier to figure it out then.

Thanks!
