RE: [Acpi] Re: shutdown on pressing the ATX power button

[Grover, Andrew]

Well, I think we're both familiar with both sides of this argument from a
few months ago. I won't rule out your proposed implementation but I'm
sceptical. Can we revisit this issue in a few months? Once acpid is more
feature-complete, we should be able to use it as a reference to discuss the
requirements an init-based power policy would have to meet.
