dont think anyone is implying that the FC releases are not "real". As
for the meaning of the words "proving ground", and the other bits, I am
using the commonly accepted definitions, as well as the commonly
accepted interpretation of what Fedora is.

I disagree with this, rather strongly. The Fedora series has had a
number of surprises for admins, for driver makers, for users, and so
forth. SE-Linux, 4k-stacks, glibc changes, etc. All of these wound up
in the supported release (e.g. the one for production environments).
Sure you can use it on your systems. Of course you can. If something
breaks on some commercial code that you might run, are you SOL? If you
don't run any commercial code, and have no liability issues associated
with using supported platforms, this is a moot point.

Depends strongly upon your level of pain tolerance, and your willingness
to occasionally deal with updates that mess up your systems. If you
have admins that can handle the support issues that arise (including
building new kernels, driver debugging, and so forth, sure, it is
"production ready". If you need to push the OS/driver support back to
the supplier of the system, no, it is not.

On the contrary, I don't think SE-Linux is "puce-and-teal color scheme".
Nor are 4k stacks (that broke many many drivers). Yes, FC introduced
those. No, it was a significant shock when stuff stopped working. Is
that really production ready? (e.g. thorough testing and bug fixes so
that there will be no surprises)

There are lots of folks out there who are spinning this to their needs.
Bottom line is (apart from Greg's company) I know of very few
commercial software vendors targetting FC-x as a supported platform. As
most folks buy systems to run software, and they want to make sure
(before they buy) that there is support (e.g. someone to yell at when
things break), most end users will likely opt for the supported releases
(where their apps are tested on, as they may have liability issues if
they use an unsupported platform (yeah, this arose recently)).
Some folks, with sufficient support expertise locally may be able to
support FC-x themselves. Thats great. Still doesn't make FC-x a
supported platform, or a production grade/ready platform (e.g. extensive
testing and burnin against critical components).
I like FC-3 on one of our Opteron boxes. Fast and responsive. I would
not recommend it to a customer unless they had an admin/staff around
with something like your capabilities, and then only if there were no
liability issues (manufacturers using commercial codes), or other
dependencies that indicated against it.
