In this case, you would be checking your own package, right, so the docker 
image cannot know in advance what the Suggests dependencies of your package are.

Adding the Suggests dependencies of all packages installed on the image is 
going to make the image much bigger. This request comes soon after other 
requests to reduce the size of the images. We should probably have a wider 
discussion and decide exactly what type of docker images we want to have. 

Use cases that have been mentioned are:

  - an image for building/checking with travis (sounds similar to Kasper's 
request above). 
    For this one in particular, small size is important as Travis has to build 
its environment 
    from scratch every time, and loading large images takes too long. 
  - an image that has the Suggests dependencies of all installed packages 
installed. 

We might want to pick a different way to decide what packages are installed on 
a given image. 
Currently we install all packages with a given biocView (Sequencing for 
example) and this leads to
very large images (sequencing = ~7.5GB).
