rc.local seems not be called anymore at boot. Annoying permissions on rc.locale are read and execute for all. rc.local can be executed from comd line by root.
running service .. service rc.local start Warning: The unit file, source configuration file or drop-ins of rc.local.service changed on disk. Run 'systemctl daemon-reload' to reload units. root@raspizw:~# systemctl daemon-reload root@raspizw:~# root@raspizw:~# service rc.local start root@raspizw:~#
But not started!!
For Raspbian (before it became RPi OS), this is the sequence that I worked out to do it, as my introduction to Systemd. Implemented as a Bash script. It convinced me that Systemd is overcomplicated and encouraged me to avoid it since.
#!/bin/bash #Enable execution of rc.local on start-up with Systemd:
chmod a+x /etc/rc.local
