Re: [HTCondor-users] Setting a whitelist of allowed containers?

Thanks Greg. I guess the question is how does HTCondor deal with requesting the ARM vs. x86 version of a container? Or is that left up to Apptainer?

The startd could certainly set a START requirements _expression_ that
would only match jobs that requested certain named containers. And
also, perhaps, advertise which ones are allowed in a separate list.
