Hello everyone, A quick strace shows that it's actually an ordering issue: /home/user is mounted in the container after /home/user/tmp. The fix is pretty simple, moving the cwd first, before the explicit --expose arguments. I'm noticing that the --expose option creates an empty tmp folder in the user's home in that case though, which I don't like, however I don't think there's any better option. Patch following. Best, -- Josselin Poiret
