Ansible question

[Miroslav Suchy]

Working on Copr, I want to replace/add one line in file. I spent more 
then hour trying various things, but I'm out of ideas.

What I'm trying to do is:

self.conn.module_name = "lineinfile"
self.conn.module_args = "dest=/etc/mock/%s.cfg 
line=\"config_opts['chroot_setup_cmd'] = 'install @build %s'\" 
regexp=\"^.*chroot_setup_cmd.*$\"" % (self.chroot, self.buildroot_pkgs)

Which in yaml language should be (with placeholders expanded):

- name: putting scl-utils-build into minimal buildroot of fedora-19-i386
   lineinfile:
     dest=/etc/mock/fedora-19-i386.cfg
     line="config_opts['chroot_setup_cmd'] = 'install @build 
scl-utils-build'"
     regexp="^.*chroot_setup_cmd.*$"

I tried several things - among all:
   - change regexp
   - do not use regexp at all as that should put $line at the end of 
file, which would work as well
   - use command module with sed, but there is too much of escaping and 
it is unreadable

Can somebody advise me what should be correct form to replace or add 
that line to mock config please?
