I am too used to typing outside of browsers. Let's try this again.
According to the module docs
<http://docs.ansible.com/ansible/lineinfile_module.html>, there is
different behaviour whether you are replacing an existing line (backrefs)
or adding a non-existent line (insertafter or insertbefore).
Insertafter/insertbefore will add a new line but not remove the old one.
If you want to replace an existing line, you can use backrefs. However, if
the regexp line doesn't match, it won't add the replacement line:
Adding to Johannes example:
> - name: "Replace hostname with FQDN"
> lineinfile:
> dest=/etc/sysconfig/network
> line="HOSTNAME={{ ansible_fqdn }}"
backrefs=yes
> regexp="^HOSTNAME=.*"
> state=present
