I’m trying to configure my host during deployment process and to give an output to the screen of what my configuration script is doing.

In RHEL6 it was easy i was echoing what I want to screen or used dialog to display the output, and only when my script was done i got the login prompt.

  • ( I used rc3.d or rc5.d folder with script name S99.myscript.sh)

In RHEL7 i can’t mimic this process. rc.local does not display my output during booting and also its not guaranteed it will run last.

I guess I need to create a systemd service file that will run my script.

But how do I output the result to the screen while booting?

And how do I make sure I will not get the log-in prompt before my script ends?
