running start-up script using systemd

[Danishka Navin]

Hi,

I have written a script which suppose to run at start-up and set a given IP.
I can see systemd service is running when I check the status but I can find
the expected result (new IP).

Is there anything wrong with the following format of the service file?

[Unit]
Description=Config IP
ConditionFileIsExecutable=<path_to_script>/script
After=network.target
StartLimitIntervalSec=0

[Service]
ExecStart=<path_to_script>/script

[Install]
WantedBy=multi-user.target

Is it ok to restart network service with the script I use?

Regards,

Systemd won't let you run 'systemctl restart ...' inside of a service
script.  It's an attempt to avoid infinite loops, I think.

The last time I tried that I had to modify my script to nohup, sleep,
and then call systemctl.
