A lot of engineers prefer Linux over Windows and would use it on there test machines if at all possible. Instead of attempting to support a wide variety of flavors, wouldn't it be better if NI would derive it's own flavor from an existing distribution and committed to having full support for all NI software and hardware for this new flavor. This would give Linux aficionados the OS they crave and NI the power to control the direction of the OS such that it makes hardware and software compatibility easier.
