At what point does Red Hat hold off on adopting Linux 2.6?
Or GCC 3?  Or GLibC 2.0?

As I said, there is a chicken-egg issue between "waiting for something
to be well-tested with many packages" and "adopting something so it is
well-tested with many packages."  This existed back in the Red Hat Linux
timeframe, and it still exists today.

That's why RHEL is essentially based on the ".1" or ".2" release.
Then it is kept fairly _static_ over its lifetime for SLA reasons.

And other "packages" distros don't have this problem?

If you find Fedora Core + repositories doesn't solve what you need
either, I think someone else pointed out that a "ports" distro, like Gentoo,
might be more of what you are looking for.  Especially if you're
rolling out lots of "bleeding edge" distros.

BTW, just so everyone knows, I support Debian, Fedora, Gentoo,
NLD, RHEL, SuSE and SLES as a paid consultant.  And I've been
a maintainer in several projects so I'm not just a "Red Hat-only
lacky" as many people believe.  In fact, I am a software engineer
at many clients (I just get stuck with the IT / configuration management
because I seem to know how to do this with Linux better than the
others around me).

So I'm very partial to using "ports" distributions like Gentoo and
BSD.  ;->

Understanding why either allows you to:  
A)  See what you can do to get the vendor to change, _or_
B)  Better recognizing what you can do to accommodate the vendor

I said it before and I'll say it again, one of the reasons I have very
much sought after -- almost always by personal reference -- it
because I can come in, look at someone's business/engineering model,
and then architect a solution that maximizes the application of a
solution while mitigating risk to any product changes.

Unless you understand how and why the vendor is doing something,
you can't either do "A" or "B" and customize the solution one way or
another.  The last thing my clients want to hear from me is "damn,
Microsoft/RedHat/etc... broke your network."

Furthermore, when architecting a solution, I can also give the client
options and say, "if you go with RHEL, you're going to run into the
re-occuring problem of X, Y and Z."  In most cases, it helps me
eliminate Microsoft from client consideration early on, but in some
cases, I actually end up rolling out a completely _non-Red Hat_
solution.

That's different, although the concepts are similiar.  There is no
vendor that can provide a solution that doesn't need accommodate
at some point in a solution.  Fortuntely, we don't have the "on-a-whim"
changes in the RHEL space like we do in Windows -- _primarily_
_because_ Red Hat _never_ mixes in "new features" mid-release.

But configuration management is _always_ an issue.  You are _never_
going to eliminate much of it even in the Linux space.  It is a necessary
evil that you must do -- and that will vary on the focus of the distro.
In fact, not doing configuration management in Linux roll-outs and,
essentially, _falsifying_ the savings on Linux with it, is the absolute
#1 reason why Linux projects fail.

Having a background in defense, I liken this to NASA's COTS (commercial
off-the-shelf) adoption in the '90s.  After Sojouner (Mars Pathfinder)
proved that GNU/VxWorks was a viable platform that cost 1/10th of
custom software/hardware development, NASA's nexgen probes started
adopting the same platforms/software as Pathfinder.

The problem on these other projects is that the 90% savings was no
longer applied to just software/hardware, but _all_ aspects of the
project's budget.  So unlike Sojouner, the QA (quality assurance) budget
was cut.  So when Mars Polar Lander entered the orbit assuming the
units in a register were miles when they were, in fact, kilometers --
because there was not the QA between two engineering teams
at two different companies several states away from each other --
I was not surprised one bit.

Configuration management is quality assurance.  You must do it and
there will _never_ be a vendor, distro or other "off-the-shelf" solution
that will allow you to avoid doing it.  Because a solution is _never_
available that is customized for you and regression tested to work
without issue.  That's just reality.

> I'm not really interested in playing a 'vendor lock-in' game.

Okay, this is the typically spiral I see people do.

They start talking about "vendor lock-in" with regards to Red Hat,
applying their experiences with Microsoft.  Sorry, this is _exactly_
the "demonization" I'm talking about.

You are comparing the world's greatest, "we lack even proprietary
standards" company to Red Hat, the absolute #1 pro-GPL commercial
company.  So there's _no_ sense in my responding further.
