SystemD services to be blocking "URGENT"

Hi all,
I am performing a customized installation of CentOS, where instead of standard Anaconda, installation wizard, I am invoking my own wizard which will collect inputs for installation
My code is based on newt (https://pagure.io/newt) and uses python3.4

I am facing a challenge that before wizard could complete, it goes to subsequent service in my case getty@tty1.service, getty.target, multi-user.target
so I get the login prompt test login:

How do I ensure, this prompt/ or my wizard completes before login prompt comes

I am putting my systemd service file contents below

Use CODE tags when posting scripts and other things of this nature, please. And see the "How to ask a smart question" link in my posting signature. This is **NOT URGENT** for anyone here. We volunteer our time, so asking for/expecting 'urgent' assistance is fairly rude.

And based on what you posted, we can't tell you anything. You don't say what version of CentOS, nor post the contents of that menu.sh file that's getting called. Chances are, there's a bug/problem in it.

CentOS version I am working is CentOS 7.4
Script invokes the wizard python program based on newt
python3 wizard.py -f config file

sorry for adding URGENT

Right...so back to "It's probably the menu.sh file you're CALLING, but haven't shown"

Yeah.

Hi all My problem got resolved, I had to ensure /etc/systemd/system/default.target points to target file which points to my service
