<br>
TL;DR: I can vouch for this.<br>
<br>
The primary problem with the interaction between the new namespace<br>
code and the automounter daemon was simply that the shared subtree<br>
flags on the root mount within the Slurm-built mount namespace were<br>
not selected with things like autofs in mind. It was marked private<br>
(no mounts out, and no mounts in) rather than shared+slave (no mounts out,<br>
but mounts *do* come in); once that was found and fixed, autofs and<br>
job containers played nicely again.<br>
<br>
There were a couple other Oopsies with regard to mount/unmount<br>
operations that were addressed at the same time. If you're curious<br>
for more detail, you can follow the links in this comment on our bug<br>
report:<br>
