Hi,
How can I find the systemd last run service I can put it in my network
application After=<last run tartget or service>?
I need my network application service to be run at last in boot, I
made After=connman and Requires=connman.service that did not work,
always failed in boot, I have to manually restart the network
application service which won't work in field operation.
Searched from Internet, there is a blog Systemd: Run it last to create
a custom.target After=multi-user.target, and put my network
application service WantedBy=custom.target, that works well, but it is
a little bit cumbersome to configure customer.target in Yocto bb file,
enabling the customer.target is called systemctl isolate
custom.target, the /etc/systemd/system/default.target link needs be
changed to from multi-user.target to custom.target. I am not sure how
it could be done in do_install, appreciate your tips.
Thank you.
Kind regards,
- JH

I'd suggest you find out what you network service actually require.

The application requires network connection to communicate services
via Internet, it could only work if the network connection is ready,
so I really want to know which system servuce run at last I could put
it in the After statement.

Adding
After=multi-user.target
to the [Unit] section in your systemd service file should do what you want.

If you app only requires network, you just need After=network.target.
Did you try that out?

Terrific, that works well, thanks Rudolf and ChenQi.
