Run python script inside /etc/rc.local doesn't work

Question

I modified /etc/rc.local on my Amazon AWS AMI

#!/bin/sh touch /var/lock/subsys/local # setup hostname properly /usr/bin/python /root/automation/initSystem.py 

so last line calls Python script that does configuration (Env variables, hostname, networking settings etc) and then does /etc/init.d/network restart

if I run rc.local manually /etc/rc.local everything is just fine

when system auto starts it doesn't work. So touch command (2nd line - worked), but python script is never executed, at least results of it's execution (setting up a hostname and restarting network interface seems doesn't work at all)

Any ideas?

We can't debug a mystery script. Does running the python script work with an empty environment? Try:

env -i /usr/bin/python /root/automation/initSystem.py 

Modify your script to capture the output of your command in the script:

/usr/bin/python /root/automation/initSystem.py > /root/init.stdout 2> /root/init.stderr 

and it'll probably contain hints as to why it failed.
