Apptainer (Singularity) on MARC Login Node - 2023/06/23

Apptainer (Singularity) containers may experience an error when

running on the MARC login node. If apptainer complains that a system administrator needs to enable user namespaces, simply run your containers inside a job.

This is a temporary measure due to security vulnerability that will be

patched soon.
