Imho acpi_poweroff or poweroff_button would have been a clearer name.
Or even 'sendkey poweroff' - it's just a button someone on the
keyboard on a lot of systems anyway. Next to the email button and what
looks, on my laptop, like the play-a-tune button :-)
I put system_poweroff into some QEMU-controlling scripts once, and was
disappointed when several guests ignored it.
But it's done now.
