[CentOS] Differences in CentOS and RHEL systems

Hi,

I was looking at the differences between the CentOS and RHEL systems, found that tuned profile is different for these OSes.
I have gone through RHEL 7 Performance Tuning Guide to see if there are more such changes, sysctl settings change which are due to tuned profile and did not find any other differences
Also took diff of /etc/* config files on RHEL and CentOS installed systems, there are RHEL subscription and bugzilla references which vary

So, are there more such system wide differences on CentOS?
