I am trying to log shutdown/reboot on a Raspberry Pi. I am running latest Raspbian. This is my setup:cat /etc/init.d/log-shutdown.sh:#!/bin/sh### BEGIN INIT INFO# Provides:          log-shutdown# Required-Start:# Required-Stop:     umountroot# Should-Stop:# Default-Start:# Default-Stop:      0 6# Short-Description: Log shutdown date.### END INIT INFOecho I ran>/log-shutdownls -Al /etc/init.d/log-shutdown.sh:-rwxr-xr-x 1 root root 258 Apr 15 20:10 /etc/init.d/log-shutdown.shls -Al /etc/rc0.d/*log-shutdown*lrwxrwxrwx 1 root root 25 Apr 15 19:41 /etc/rc0.d/K01log-shutdown.sh -> ../init.d/log-shutdown.shls -Al /etc/rc6.d/*log-shutdown*:lrwxrwxrwx 1 root root 25 Apr 15 19:41 /etc/rc6.d/K01log-shutdown.sh -> ../init.d/log-shutdown.shAfter running sudo shutdown -r now and waiting for the Pi to reboot, /log-shutdown is not written to. Manually running sudo /etc/init.d/log-shutdown.sh does write to the file. What am I doing wrong?
Why is a script in /etc/rc6.d not run on reboot?
linux;shutdown;init.d
So. I appear to have found a solution, but I haven't a clue why it's needed, as it isn't on Ubuntu. /etc/init.d/log-shutdown (I removed the .sh) now looks like this:#!/bin/sh### BEGIN INIT INFO# Provides:          log-shutdown# Required-Start:    $remote_fs# Required-Stop:     $remote_fs# Default-Start:     2 3 4 5# Default-Stop:      0 1 6# Short-Description: Log shutdown date### END INIT INFOcase $1 in  start)    touch /var/lock/subsys/log-shutdown    ;;  stop)    date +%s > /data/log/log-shutdown    ;;  *)    echo Usage: /etc/init.d/log-shutdown stop    exit 1    ;;esacThe important bit is touch /var/lock/subsys/log-shutdown, which tells the init system that log-shutdown is running, so it bothers to run the stop script on shutdown/reboot. I think.
