another alternative:  bifurcation.  an install and play latest os version, and 
a barebones version intended as a dedicated machine controller.  my guess is 
that there are far more functional types of hardware in the world than there 
are versions of software which can live happily on the hardware types.  
otherwise 'obsolete' cpu habitats could be seen as an unexploited resource.

We've had variations of this discussion before.

My principal question is always, what do you want your real-time 
EMC2-equipped computer to do?

If it is intended solely to control a machine, then most of Ubuntu is 
unnecessary. Others have posted to the Wiki their successes in bringing 
EMC2 to minimalist Linux environments, and we could go that route. 
Indeed, I'm planning to do that myself once I get around to finishing my 
real, headless controller (as opposed to my bench-test controller). 
Instead of starting with a distribution packaged by someone else, we 
could create one ourselves, starting with Linux From Scratch (LFS), 
resulting in the absolute minimum environment needed to build and run 
EMC2. To my mind, for controllers there are only two reasons for 
thinking about upgrading the O/S: 1) a new version of EMC2 with features 
I want requires it or 2) a new motherboard/CPU/peripherals-combo to 
replace an old one requires it. Upgrading for just the sake of getting 
the latest flashy desktop seems ludicrous.

On the other hand, if your EMC2-equipped computer is intended to support 
Internet telephony, browse HackADay.com, run all your favorite CAD/CAM 
applications, keep the books, play music videos, etc., and, 
oh-by-the-way run a machine tool (I think this is the wrong approach, 
but that's just me), then you're likely to want to start with a full 
distribution like Ubuntu, so why not stick with Ubuntu for as long as 
possible? The number of applications that are supported in Ubuntu is 
staggering. I don't think any of the other distributions are immune to 
the pressures of the marketplace (even with "free" software there's a 
marketplace, it just has a different reward system) and won't get 
enamored of Unity or their own version of a touchy-tablet desktop 
environment. We can strip the distribution down if we like, or, instead 
of subtracting from the full edition, we could add to the server 
edition. Whatever. This kind of remastering used to be very hard but 
it's gotten easy in recent years. And if Ubuntu goes completely off the 
track, there are other, less popular distributions so similar in the 
technologies EMC2 depends on that the transition would be almost effortless.

Frankly, if I wanted to lie awake at night, I'd choose to worry about 
the teams developing real-time extensions to Linux in the face of rapid 
changes to the Linux kernel or about the future of AXIS as both desktop 
environments and windowing systems evolve.

Just my 2 cents worth.

Regards,
Kent
