Leftover files in /tmp about rocker

Dang! Touche -- /tmp/downloaded_package is definitely a littler issue.

I also now remove the svn checkout when building r-devel, yet the container is still humongous. Should we consider removing the packages needed to build it, if we perceive of the container as a pure 'run this' appliance?

For a (much) smaller image for r-devel, can you just skip installing texlive?

Also, I think if you don't want the svn checkout to take up space, you can put the entire checkout/build/install/remove for R-devel in one RUN statement.

When I do docker images --tree, this is what shows up on that branch:

The ~750MB increase is texlive; the next 130MB increase is the svn co, and the 120MB increase after that is the make.

In the new 'drd' (== 'docker r-devel daily', approximately) I already remove the svn artifacts, removing all of texlive* (or not even installing it in the first place) may be next.

Turns out you need some texlive or the build fails. So that saved a bit, next on the list was to .. actually uninstall some of the packages needed for building.

Which didn't change much. Still at 1.15 gb.
