I guess the question which is bothering me; is in these automotive and perhaps (aeronautical ?); applications of OS's where bugs, hacks and security holes really are' life and death' issues; are the security holes which have been found; just programmer carelessness or reflective of the seemingly never ending generation and discovery of bugs and security glitches ? A microkernel OS would probably be a good option.
Russell I am quite surprised to hear you suggest this, as it would seem to eliminate: -obviously Windows; but also Linux leaving only QNX from the group of OS's mentioned . I have come to associate your name with SELinux a byword for, security and stability .Is it the need for a real-time OS in such applications rather than the requirement, for security and stability which is the basis for this suggestion ? Curiously there seems to be a convergence here with such science-fiction proposals as 'fly-by-fibre' which envisage the replacement of the weight and topological complexity of the aircraft wiring harness with a single ultra-high performance fibre optic net work and a single high voltage DC supply with solid-state DC-DC conversion at each controlled device. Can't find the original reference to such an idea but it cetainly seems implicit in: http://www.avoptics.com/fohec/2012/Presentations/05.pdf regards Rohan McLeod
