You're splitting hairs. Microkernels do offer practical advantages by virtue of their architecture, while suffering from other drawbacks again caused by their architecture.
I'm not trying to "split hairs", I'm trying to address a problem that has repeatedly made my life difficult -- people seeking particular technologies instead of solutions.
But since that has obviously made some people upset, I'll trouble you no more about it. I'm sorry to have intruded.
Why do you automobile engineers keep talking to each other about pistons and transmissions, and all that nonsense, it's absurd. I just want a car that gets me from A to B and doesn't use too much gas. I don't see what that has to do with engine seals.
Right here and now, we're doing it because it's fun. At the end of the day, most of us go back to practical solutions, but we have to get this stuff out of our system. :)
Second, the original context of that conversation isn't kernel architectures, but what particular kernels "offer".
Discussing kernel architectures as if they're a practical advantage is surreal.
