CentOS guarantees binary compatibility with RHEL. That's why it matters.

So does SL. They basically compile the same SRPMs and publish the result.

The fact that people keep qualifying this sentiment with "basically" and "virtually" does not instill much confidence.

[viraptor]

Because they remove RedHat logos and other trademarked bits, then put SL/CentOS bits in. Same approach in both distros.

So they compile from the same source redhat uses, but change the trademarked media. Is that good enough?

If I was running a billion dollar company I would not be using a product that only promises "basically".

Billion dollar companies spend money to buy Red Hat Enterprise Linux licenses, because promising 100% binary compatibility with RHEL isn't as good as being RHEL. If CentOS is even an option, Scientific Linux should be as well.

[baudehlo]

I work for a billion dollar company that uses CentOS because RHEL's licensing is too expensive.

How do you get support? Are these mission-critical systems?
