I don't want to start over from scratch.
There are several ways I could change the monitor.service so it would fail or run without booting:
pi@raspberrypi:~ $ sudo systemctl --full edit monitor.service pi@raspberrypi:~ $ sudo nano /etc/systemd/system/monitor.service pi@raspberrypi:~ $ systemctl stop monitor.service
edit the app monitor.py so it won't have the option to reboot.
change a value in the file cmdfile.txt so it won't take the reboot path in the app.
But it already reboots before any of the above options are available.
I Have a limited number of options:
Since I don't want to reload the system NOOBS.
1) hold down Shift when the raspberry pi screen comes up.
2) select Edit config
3) click cmdline.txt
4) add " init/bin/bash" to the end of the command line.
5) click OK
6) click Exit
7) it will reboot and stop at the bash.sh prompt # (I have to push enter to get the prompt)
At this time I can
sudo nano monitor.py
I can not modify them: [ file 'monitor.py' is unwriteable ]
I can not change their permissions:
chmod 666 monitor.py
chmod changing permissions of 'monitor.py' Read only file system
I suspect these are images only before being loaded into the system.
Is there anything in config.txt that I could un-comment or add?
I need a different option than "
init/bin/bash" in the command line that runs later in the boot process and allows me to modify files.
Or I need to know how to enable bash.sh to modify files. -- I suspect the files are not loaded yet.
I would like to use "
systemctl stop monitor.service"
I would like to stop boot right before monitor.service runs.
exit takes me to a dead end and I can turn the power off.
I suspect I could change the files if I loaded them on Linux file system for Windows.
I see where I could change it to read/write:
mount -o remount,rw /dev/mmcblk0p2
but I am not ready to take that leap and my partitions are different (or I don't understand them)
I keep looking for a magic command that asks me
"Hey Bozo, do you want to run your bad, screwed up monitor.service?"
And I'll chose No.
Or a set of keystrokes that stops autoload right after the raspberry pi screen opens and before idle.
