TL;DR: I can vouch for this. 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.
