Centos – The real differences between Red Hat Enterprise Linux (RHEL) and CentOS

centosredhat

I know that "the vast majority of changes made (by CentOS team ndr) will be made to comply with the upstream vendor's re-distribution policies concerning trademarked names or logos"

But I'm looking for a way to measure the real differences between RHEL and CentOS. My goal is to demonstrate "scientifically" that is possibile to use CentOS for development and testing purpose and use RHEL in the production environment.

Any suggestion?

Thanks in advance.

Short of doing installations of both and running a fancy diff between the two and manually picking through the output, there's no real way to prove to most people that they're the same. Yes, they use the same compiler, and the same linker, and the same libraries, all with the same options, but many people don't see induction as proof.

Centos – Configuring the hostname on Red Hat Enterprise Linux

The box in your example will have hydrogen.lan as its hostname, not hydrogen.

The only way I know of to have hostname return the short hostname and to have hostname -f return the FQDN, is to use both the mentioned options.

So add HOSTNAME=mybox to /etc/sysconfig/network and add

10.10.10.10 mybox.example.com mybox

to /etc/hosts. I like having hostname and hostname -f return different things. By default, Anaconda sets it up like you have it set up now.
