SystemV-like Init Scripts

If you have custom packages that make use of the old SystemV startup scripts, you can use the following files to make use of such scripts.

In /etc/systemd/system/cpsc-initd.service

[Unit]
Description=CPSC SystemV-like startup scripts
ConditionFileIsExecutable=/usr/local/sbin/cpsc-initd

[Service]
Type=oneshot
ExecStart=/usr/local/sbin/cpsc-initd
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99

[Install]
WantedBy=multi-user.target

In /usr/local/sbin/cpsc-initd:

#!/bin/sh

#
# This script will execute all scripts that are placed under
#    /usr/cpsc/boot/startup/
# on runlevels 345
#
# On the first initial boot (after install), scripts under
#    /usr/cpsc/boot/firstrun/
# will execute before the startup scripts.
#
# This script runs after network has been brought up, but
# before any services starts. (S29)
#
# This script will also create a file at
#     /usr/cpsc/boot/initialized
# if it doesn't already exist and will run the firstrun scripts.
#
# Why: Simplifies how scripts are added to the startup process.
#   Also makes it easier to run certain scripts one time.
#
InitializedFile="/usr/cpsc/boot/initialized"
FirstRunDir="/usr/cpsc/boot/firstrun/"
StartupDir="/usr/cpsc/boot/startup/"

    # Every script that gets executed will be renamed to start with a K.
    # Thus, it's possible for your firstrun scripts to reboot the machine
    # without having it loop infinitely.
