why do we install rdma-core-devel here? Who is to say someone wants to run RDMA stuff

Having rdma-core-devel installed affects how OpenMPI is configured (--with-verbs or --without-verbs).

I'm happy to remove it, it's probably overkill here, but I don't think it hurts to have it installed?

just wonder if we need to install this in the base - but ok... premature optimization I'd say

Again, I don't think it hurts much, except for size of the container a little bit?

Stripping it out is not a huge deal for the tutorial, and if it's there you can add rdma-core-devel in another image on top of this one, and rebuild OpenMPI (and everything that depends on it...), if you really want IB support, but that's a hassle.

let's keep it for now... and put a pin in it for a later discussion
