Subject: Start IOC automatically at boot

Happy new year!

I am trying to install systemd-softioc (procServ) as outlines here

https://github.com/NSLS-II/systemd-softioc. I followed the instructions

and successfully installed it on my Raspberry Pi. I installed the IOC

and can manually start the softioc, however I am not able to start the

IOC using manage-iocs. I get the following output:

softioc@raspberrypi:/epics/iocs/testIOC2$ sudo manage-iocs start

testIOC2

Starting the IOC 'testIOC2' ...

Failed to start the IOC 'testIOC2'; type 'sudo journalctl -xe' for

details.

Below is my config file and output from the journalctl

Config

---------

NAME=testIOC2

PORT=4053

HOST=raspberrypi

USER=softioc

CHDIR="/epics/iocs/testIOC2/iocBoot/ioctestIOC2"

EXEC="$CHDIR/st.cmd"

The softioc testIOC2 contains a few records which get updated from a

python script. Which brings me to my next questions. Is there a way to

automatically start the python script with the ioc?

Thank you very much for your help,

Regards
