Start Linux daemons (services) in WSL 2 and WSL 1 using Windows Task Scheduler on Windows user logon

start-services.sh

#!/bin/bash

# Start Linux daemons by starting WSL on user logon
#
# Usage:
# 1)	Edit and save this bash shell script as /root/.bin/start-services.sh AND MAKE IT EXECUTABLE (chmod +x)
#			(or wherever but remember to use the correct path in Scheduled task argumrents)
#
# 2)	Set up a Windows Scheduled task to run this script via wsl.exe on user logon;
# 		Action - Start Program
#			Program/script: C:\Windows\System32\wsl.exe
#			Arguments: -u root -e /root/.bin/start-services.sh
#
# Note #1: The `-u root` part is needed to run the script as root user. Otherwise it won't work.
#
# Note #2: Be aware that if you're running a local DNS server in Windows
#		(dnscrypt-proxy or Acrylic DNS Proxy) on TCP port 53, and *WSL 2*,
#		you'll also have to stop those DNS service(s) before running wsl.exe or WSL2 will fail to start.

# Space-delimited list of daemons to start
DAEMONS="rsyslog dbus cron atd ssh nullmailer"

# Log file to later check what's gone down (or up)
