The primary problem with the interaction between the new namespace code and the automounter daemon was simply that the shared subtree flags on the root mount within the Slurm-built mount namespace were not selected with things like autofs in mind. It was marked private (no mounts out, and no mounts in) rather than shared+slave (no mounts out, but mounts *do* come in); once that was found and fixed, autofs and job containers played nicely again. There were a couple other Oopsies with regard to mount/unmount operations that were addressed at the same time.
