Hi Scott,<br>
<br>
It's indeed an interesting question. The answer is quite useful in
knowing the value of RHEL in a commercial setting.<br>
<br>
Red Hat Enterprise Linux is created by period forks of the Fedora
Linux project. Fedora is the community project funded by Red Hat
that contains the newest packages and is tested across a wide
audience. Many bugs are present when packages are updated across
the board and Fedora is rebuilt by Koji (their build system) to
ensure that there are no big breakages with the build process. New
technologies are quickly adapted in this software channel.<br>
<br>
Every 2-4 years, Fedora is forked into the new RHEL version. RHEL 5
was forked from Fedora Core 6 and RHEL6 was forked from rawhide
somewhere between Fedora 12 and Fedora 13. <br>
<br>
It is said that you can tell the direction where the next RHEL is
headed by keeping an eye on the Fedora distribution. Indeed, by
using Fedora 10/11/12/13 I was quite prepared to operate RHEL6 and
how it differed from RHEL5.<br>
<br>
Once the fork for the creation of a RHEL release forms, there are
generally no new packages added to it (there are exceptions:
recently X.org 1.10 was updated in RHEL 6.2 and
Firefox/Xulrunner/Thunderbird were all updated to 10ESR from
3.6.x). Instead, the packages stay at the same version for the
duration of that RHEL branch. There are updates but these are
generally broken down into two categories: 1) Security updates and
2) backports.<br>
<br>
#1 is very important. Anyone running Fedora after that versions EOL
will no that no future updates are released for that version leaving
you to run a release that has effectively been abandoned or update
to the new release (complete with new packages and usually a whole
new set of bugs to work around).<br>
<br>
#2 is equally important as it allows Red Hat to support newer
hardware that was not available at the time of release of the
original Fedora that that RHEL version was based on. Adding support
for new processors such as Sandy Bridge and porting new features
generally only found in newer kernels and other packages are
provided in RHEL point releases. Though the kernel release stays at
2.6.32, for instance, it is hardly the vanilla upstream 2.6.32.
Instead it has many features backported from a future kernel.<br>
<br>
Hope that answers your question.
