It's a very good indicator! That actually says a lot..

OK - I guess my question was if proprietary Red Hat software has to be
stripped out from CentOS or is it purely logos and the word "Red Hat".

If software is removed would an administrator of the server have to know
if the server was RHES or CentOS when working on it... Does that make sense?
