I absolutely believe that to be a truism!
HOWEVER … that statement is incomplete and therefore misleading!
You must
-
first choose what you plan to do,
-
identify the tools with preferred GUI interractions,
and only then
- choose the Distro(s) on which those tools are verified functional in the way you want them to be!
Otherwise, the consequence is likely Distro-hopping … in search of things working the way you want!
The specific domain of “Real-time Linux” is one where I question the use of the word “Linux” itself, since the Official Kernel is not coded in a structure dictated by real-time requirements.
For real-time, you quite literally need to “strip out” and “replace” key process structures to correctly work as real-time, which is scanning multiple input channels, simultaneously, transforming/processing the values simultaneously, then acting based on priority in a defined-sequence within an absolute-limit timed cycle.
That is not how “standard Linux” is coded or operates.
