It will at some point, not just right now if you don't use RDMA. Which may be soon if the packages start pulling in RDMA dependencies and your adapters support it.

All of those modifications will require rewriting scripts to take care of corner cases, even if you're not hitting them right now. The question is, how much will you have to modify them? In that case above, the fact that you can't just grep on a brick name or on ^Brick and get one unique result per brick will require quite a lot more logic to handle than adding one field on the line.

I believe that brick entries should stay unique, and that the RDMA port should be encoded some other way (and not in the name -- see my previous email).
