In https://support.schedmd.com/show_bug.cgi?id=9282#c6 Tim mentioned this env variable SINGULARITYENV_SLURM_CONF, what is the usage/syntax for it? I can't find any reference to this. I'm running into the same issue mentioned there.

That's an Apptainer (formerly singularity) feature. See https://apptainer.org/docs/user/1.3/singularity_compatibility.html#singularity-environment-variable-compatibility . So it should be setting SLURM_CONF inside the container.

Thanks in advance!
