I don't see ruby-gofer in any of the cloude or pulp (rhui-branch) spec files.. 
Is it possible this is getting added by a release engineering process?

Thanks

It is. What packages get included on the ISO is driven by a "comps" file, a snippet of which looks like this:

If you want me to remove ruby-gofer, I can omit it from this file and generate another ISO.

This isn't a big deal.. Next time you cut the iso for bug fixes etc.. yes please remove ruby-gofer from the comps file. 

Thanks Jay!
