Correction: the -d switch sets how long newapc will hang around waiting for; the length of time that the UPS waits before shutting down is set using upsct2. I've used -d 3 so that newapc exits quickly, the shutdown completes, and the PC powers down. > You shouldn't have any fear of the deadlock, since the smart APC > UPSes obey the killpower command even if the power returns.
