I think I just figured something out; Why people keep posting here saying they've downloaded Red Hat 9.
This person says they're using 'RHEL 9'. They are not using RHEL 9. RHEL 9 does not exist. The latest version of RHEL is 6.
People are failing to understand the difference between Red Hat, the free distribution that was around until 2003 before Fedora Core (now Fedora), and Red Hat Enterprise Linux (RHEL), which is Red Hat's current you-have-to-give-them-money-for-it distribution. They see 'Red Hat' and see that the highest number available is 9 and download it. I've no idea from where. It's available for download here but the warning about it being out of date is quite clear.
Or maybe it's something else entirely. Whatever, there's got to be some reason like this because the number of people who post saying they've just installed Red Hat 9 is way, way, higher than it should be.
