Yeah - with you so far :)

Well subject to definitions, but why

Not sure what you are getting at here ?

Given the importance of the systems any config change usually is reboot due
to human design limitations and system complexity causing 'imponderables'...

During take off and various other mission critical tasks the software
can't be rebooted and is not subject to config changes - one would hope...

There are up to 5 computers on board and in a voting arrangement so
a config change to either must be synced with all the others - sure, this can
occur after a mission critical task is over - ie. A reboot could occur when
in orbit and no thrusters need to be deployed etc - But I can't see why this
is relevant to linux and the initial enquiry ?

Highly presumptuous of you - don't use Windows NT in any form, why say that ?

I'm not telling you anything about MS, thats not what I said at all - Eh ?

I can't understand your statement about "backwards, could you rephrase
it please ?

What am I very wrong about ?

All I've said (and intimated) is that a serious OS design should not need a
reboot after a simple config change - for the simple example that a mission
critical task could be in execution at the time of a non-relevant config
change, for sheer efficiency it would not be sensible to halt/suspend the
mission critical task - the OS designer should be able to
assign and reassign config issues without the need for a reboot...
