A great/easy solution for users would make use of Docker volumes for the CVMFS cache. To be able to share volumes among containers (and thereby document a single command to invoke containers from images) we should explore the use of an alien cache. Going by memory, the command would then look something like

docker run -it --privileged -v cvmfs:/var/cache/cvmfs -v /Users:/Users ligo/shell

where cvmfs is the reusable volume stored on the user's workstation.

The present solutions manually create bindpoints inside the image and rely upon a startup CMD that mounts them one-by-one at container instantiation. A better solutions would be to use autofs. This will require the use of a container service solution like supervisord or dumb-init. Solution will more or less get rid of /etc/fstab and replace mount -a with the invocation of autofs.
