You no longer need to do any of the above; the bioconductor containers now behave
like rocker's in this regard (and the web page has been updated accordingly).
You will need to re-pull the image:
docker pull bioconductor/devel_sequencing
Then you should be able to do
docker run -e USER=$USER -e USERID=$UID -v /home/data/Dropbox/work/matrix/mr_bioc/matrix_rider/:/opt/matrix_rider -p 8787:8787 bioconductor/devel_sequencing
Then log into Rstudio as user 'data' with password 'rstudio'. And you should be able to read/write the files in /opt/matrix_rider.
