The reason I ask is this: We've got an OS X box in a very remote
location that has pretty flaky power. We've got a UPS, but there are
times when even that isn't enough. The problem is if the UPS
software shuts down the machine, it will not restart once power comes
back. The *only* way to get it to restart is to press the power
button, and trust me-- given where this machine is, that's a serious
pain the butt. The same behavior is displayed with halt(8) and
any other number of commands I've tried.
So my thought is to modify the UPS scripts to "almost" shut the
machine
down, and then just let the power fail. The "automatically restart
on
power failure" should then catch the machine and allow it to come
back
on its own.
This exact behavior is built in starting with Mac OS X 10.3.3, both client and server. If your UPS supports the USB Power class the default behavior should just work (file bugs if not). Third parties will likely rev their UPS support to use this feature--check with your vendor for more details.
