[Beowulf] Contents of Compute Nodes Images vs. Login Node Images

At least here at Harvard Research Computing we run the same 
environment/OS on both login and compute.  We've found it to be easier 
to deal with from a user perspective.  That said our login nodes are a 
different hardware than our compute, so if people want to build stuff 
optimized for specific architectures we tell them to start up an 
interactive session on the hardware they want to run on to build.

From what I knew/conventional wisdom, sites generally place pared down node images on compute nodes, only containing the runtime. I’m curious to see if that’s still true, or if there are people doing something else entirely, etc.
