I would be very unhappy of such change. For example on my laptop (Sony Vaio VGN-C1S which is now several years old) the FreeBSD ACPI implementation (at least on FreeBSD-7.2) is such that, trying to poweroff with -p doesn't succeed to really poweroff, but wedges the machine. One needs to remove the battery to regain control and to be able to power off using the power button. No need to say, suspend-resume does the same. And as a point of comparison everything works OK under Ubuntu. -- Michel TALON
