Heater, I think is some fear about what can go wrong upgrading to Stretch because of programs have on raspberry and may be incompatible with Stretch. Long ago I start with upgrade but when settings about networking starts to ask me question like do you want blah blah, I did not understaind all question and I did not continue...Heater wrote: ↑Sat Jun 22, 2019 7:41 amWhy are you using Raspbian Jessie when it has been superseded by Raspbian Stretch for nearly two years?
The preferred way to start non-GUI programs is to use systemd. You only have to create a little simple systemd service file to do that.
For example like this: https://www.raspberrypi.org/forums/view ... 61#p921354
I can't see how system start up knows whether it is restarting from a power failure or warm reboot.
I think I do not have code that needs to do anything on network... maybe some imported modules from python... i dont know
The trouble is that they do not rewrite and test my applications. I got more or less my camera working when the the PI3 came out - the conversion was a nightmare (because of permissions).

maybe is just coincidence, but couple of times...
When reboot my Raspberry pi after update and so, just regular (Raspbian Jessie) it reboot with my start script (autostart).
But when electricity goes down and came back, autostart does not start anytime.
Is there another Raspberry start mechanism on reboot or start no regulary?
Upgrading from previous releases is not supported or recommended, and now you know why. Hopefully you made a backup.
o yes, this will be my next step, someday, with fresh install.HawaiianPi wrote: ↑Mon Jun 24, 2019 8:24 pmUpgrading from previous releases is not supported or recommended, and now you know why. Hopefully you made a backup.
Best bet is to copy any configuration files, scripts and data you need and start over with a fresh install.
