I've been trying to understand the foregoing discussion so that I can shutdown my pCP LMS server(s) safely. I'd appreciate guidance on whether I've got it straight. >From the 'gpio-shutdown' section 'here' (https://github.com/raspberrypi/linux/blob/f70d3cee7ea9e6411559cc75e3882d4703752dfe/arch/arm/boot/dts/overlays/README#L728): > The default > configuration uses GPIO3 with a pullup, so if you connect a > button between GPIO3 and GND (pin 5 and 6 on the 40-pin > header), > you get a shutdown and power-up button. So I believe I need to enable the gpio-shutdown overlay on the tweaks page, and specify a pin number - I assume this replaces the default GPIO3 mentioned above. With a button connected between the specified pin and GND, a press of that button will call the pcp-powerbutton.sh script in /home/tc. That script will safely shut down pCP, issuing a 'halt' command to prevent corruption of the SD card caused if prefs or cache are being written when the power is cut. If I'm on the right lines, should that button be a momentary button or a latching button? Does pCP restart when the pin is grounded a *second* time, or when the connection to ground is broken? If a momentary button is required, that button should presumably *not* be configured as part of an sbpd setup.
