Their clones are also fascinating. Like Fedora, they've felt free to add
features (such as the mock build system and the NTFS enabled kernels available
in their yum repositories), and their 'yum' software publishing setup works
considerably better than up2date or up2date-wearing-grandma's-clothing
disguised as the yum-rhn-plugin package in RHEL 5.

That said, the RedHat FTP site is usually wildly overburdened. Look for a
local mirror for better download performance, one that supports 'rsync' rather
than FTP so that you can update a local mirror.

Fedora Core ain't a clone of RHEL, but the testing ground for RHEL, so
what is done in FC may appear in RHEL.

Well, yes. They're also not bound by the 'must not commit major upgrades'
requirements of a commercially supported OS. So CentOS 4, for example, had a
published upgrade to PGP 5, and it's freeware supported on top of the existing
infrastructure. And some things from CentOS get ported over to RHEL: take a
look at the timeline and sources of revisions for the DVD installation image
building tool for an example of tools migrating back and forth and improving
in the process.
