Post-shutdown hook for UPS shutdown?

Hi Folks, I need to execute a script (which tells the UPS to turn off) *after* the system has come to a safe halt from shutdown -h. I can't place the commands in /etc/rc.shutdown because this is too early in the shutdown sequence. Unfortunately, the UPS in question (APC Back-UPS 650) is not a "s

You'd like have to hack the kernel. There are hooks in the kernel to execute very late in the game. I even think there is one to do things just before halt that you could use to power things off completely. If this is a UPS, and the signal is several serial characters, you'd have to poll the ser

Hello! See sys/alpha/isa/mcclock_isa.c: It has attach (which allocs resource), but not detach. Also, it doesn't save the rid in the softc. I wonder, if the generic detach function is capable to clean up the resource without knowing the rid, or if this is a bug. If so, I'm going to write patches

How do you control the shutdown? If it is a simple logical signal, i.e. either high or low voltage, perhaps the easiest way would be a hardware solution. It could be as simple as a diode, a large capasitor and a resistor. Your local electronic supplyer could probably build a delay circuit for a
