The configuration currently at different CRAN machines is just a sample 
of what your users might have, just an example of a setting packages 
should be able to deal with. Some users might also still have FC36, some 
might have another Linux distribution (possibly still supported), which 
has older software than that.

I wouldn't recommend spending time tracking which version of which 
software CRAN systems currently happen to have, but rather making sure 
packages can deal with different versions (possibly with some in a 
restricted way, possibly making some hard requirements when necessary).
