And what exactly is the argument that this is the way it should be
Why can't it just rely on the kernel to provide final answer to "to reboot
or not to reboot, that is the question"?
At the end of the day, it's the kernel that decides whether it will really
ultimately ask the platform to reboot.
If, for whatever reason (which might be completely invisible to userspace)
kernel decides not to do so, userspace has to be able to recover from such
failure in any case.
