This solves a problem with bind-mounts when the containers are holding files descriptors open. At the same time this makes the template more robust to puppet changes since new config files will be available in the containers without needing to update the templates. Closes-Bug: #1698323 Change-Id: I857c94ba5f7f064d7c58df621ec5d477654b9166 Depends-On: I78dcec741a941dc21adba33ba33a6dc6ff1d217c
