If your UPS can't do that, maybe it is time to look for alternatives :) It's trickier than you think. For instance, the power might go out, the computer might shut down, then the UPS would drain the batteries and shut down. Next, the power flickers back on, UPS starts up and turns on the computer, and the power goes out again---but because UPS battery is empty, the computer crashes hard. Such power flickering is actually fairly common in brownouts. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
