No. Once it realizes it can't do any work it cleans up and umounts the
tmpfs. What I will do is add some debugging into poudriere so if it hits
the issue it will try to analyze it a bit and gather some more data.
Hopefully the user running it will report it back to us.

If I can find a way to reliably reproduce the issue I will do that.
