python startup.py

[qaqaqa288]

Hi.
I trying to get work pyhton script.
There is file startup.py, is it correct to put there line:
#!/usr/bin/python

do whatever you need to do here

by default this does nothing

/home/pi/buttons.py &

To run script in background, if my python file is located boot/crankshaft/buttons.py in SD card?

I also found that the script is killed about 30sec, and need to put: add "RemainAfterExit=yes" to /etc/systemd/system/user_startup.service after ExecStart in section [Service] - but cant find the file location?
