I agree to that part. >Even the concept of a timeout before restart makes little sense -- the >console output has been sent to an external daemon so it shouldn't get >lost like it would if it was printed to vga console and you did a real >physical reboot. But not completely here: If I don't have a serial console attached (in fact I never even tried to), then the information *IS* lost. Hence this should still be configurable, but you may clearly chose a default mode that in fact does reboot immediately. Further, as indicated, x86_64 behavior is different from i386's, which already points to pre-exisiting consistency issues.
