Jinja2 Configuration Concern with {{ fqdn_hostname }} and .conf file

[Heather Luna]

Hello! 

I have a configuration (.conf) file that I'm attempting to manipulate by adding the {{ fdqn_hostname }} ONLY for the serverName piece, the rest of the information like the SSL password is something that's going to change across my hosts. How do I edit just the one line and keep the rest of the configuration file in tact? I'm concerned that if I use a jinja2 template and simply specify serverName = {{ ansible_fqdn }} that it's going to write over the other information and simply keep that one line rendering the rest of the configuration file useless.

Thanks!

Sounds like you are looking for the lineinfile module?
