Initially I was using Ansible's `lineinfile` module to do exactly that. It's pretty trivial to do if you want to compare true Apples to Apples. Here's an article with some examples: http://fabian-affolter.ch/blog/the-lineinfile-module-of-ansible/ http://fabian-affolter.ch/blog/the-lineinfile-module-of-ansi... However, I wanted to show the actual process I went through. Editing the file in place seemed silly to do with Ansible, so I went with putting the config file in version control and copying it over. That also had the benefit of showing how Ansible encourages better practices than shell scripts. Of course, that's totally subjective, so for some folks that use shell scripts, they may already know to put their config files in version control. However, in practice, I've not seen that be the case.
