Is CentOS exactly the same as RHEL?

view full story

http://unix.stackexchange.com – I'm sure this question has been asked again and again elsewhere (I did not find anything specific to CentOS vs RHEL in SE), but I would still like to ask and confirm a few specific points. I am well aware that CentOS removes all RH trademarks, logos, etc. and is based on the same codes with packages built by the community. Are the packages built for CentOS exactly the same? Will the contents of the packages and the behavior of the programs be identical to those found on RHEL? What is RHN other than a medium for license registration? What is it to CentOS? I'm an Ubuntu desktop user. Attend (HowTos)
