The following is mostly taken from the example published at https://mkaz.com/2013/07/03/run-script-at-start-on-debian/

Write an init.d script according to the the dependency-booting specification (see at https://wiki.debian.org/LSBInitScripts).
, say it `foo.sh`. Place the script under `/etc/init.d`.

    ln -s /root/scripts/foo.sh /etc/init.d/foo 

Update the runlevel directories under `/etc/rc*`:

    update-rc.d foo defaults
    

#! /bin/bash

### BEGIN INIT INFO
# Provides:          foo

case "$1" in
  start)
    echo "Starting Foo..."
    sudo -u foo-user bash -c 'cd /path/to/scripts/ && ./start-foo.sh'
    ;;
  stop)
    echo "Stopping Foo..."
    sudo -u foo-user bash -c 'cd /path/to/scripts/ && ./stop-foo.sh'
    sleep 2
    ;;
  *)
    echo "Usage: /etc/init.d/foo {start|stop}"
