How I automate the slaughter of the Official Raspberry Pi's Debian-based OS to create reliable headless, embedded systems

The configuration of the Pi is not automated but the little script to configure JACK is similar to what I already do:

#!/bin/bash

## Stop the ntp service
sudo service ntp stop

## Stop the triggerhappy service
sudo service triggerhappy stop

## Stop the dbus service. Warning: this can cause unpredictable behaviour when running a desktop environment on the RPi
sudo service dbus stop

## Stop the console-kit-daemon service. Warning: this can cause unpredictable behaviour when running a desktop environment on the RPi
sudo killall console-kit-daemon

## Stop the polkitd service. Warning: this can cause unpredictable behaviour when running a desktop environment on the RPi
sudo killall polkitd

## Only needed when Jack2 is compiled with D-Bus support (Jack2 in the AutoStatic RPi audio repo is compiled without D-Bus support)
#export DBUS_SESSION_BUS_ADDRESS=unix:path=/run/dbus/system_bus_socket

## Remount /dev/shm to prevent memory allocation errors
sudo mount -o remount,size=128M /dev/shm

## Kill the usespace gnome virtual filesystem daemon. Warning: this can cause unpredictable behaviour when running a desktop environment on the RPi
killall gvfsd

## Kill the userspace D-Bus daemon. Warning: this can cause unpredictable behaviour when running a desktop environment on the RPi
killall dbus-daemon

## Kill the userspace dbus-launch daemon. Warning: this can cause unpredictable behaviour when running a desktop environment on the RPi
killall dbus-launch

## Uncomment if you'd like to disable the network adapter completely
#echo -n “1-1.1:1.0” | sudo tee /sys/bus/usb/drivers/smsc95xx/unbind
## In case the above line doesn't work try the following
#echo -n “1-1.1” | sudo tee /sys/bus/usb/drivers/usb/unbind

## Set the CPU scaling governor to performance
echo -n performance | sudo tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Except that I don't stop the services, I remove the corresponding packages...
