Grepping and looking around, i also noticed that the config file
services_lbaas.conf contains build path:

----- s n i p -----
# Jinja template file for haproxy configuration (string value)
#jinja_config_template = /home/zigo/sources/openstack/mitaka/neutron-lbaas/build-area/neutron-lbaas-8.0.0/debian/tmp/usr/lib/python2.7/dist-packages/neutron_lbaas/services/loadbalancer/drivers/haproxy/templates/haproxy.loadbalancer.j2
----- s n i p -----

And the actual 'haproxy.loadbalancer.j2' file is not included in the package
(which should probably be in the 'python-neutron-lbaas' package).


Looking at the source directory

  neutron_lbaas/services/loadbalancer/drivers/haproxy/templates

there's two additional files there, that should probably be included as well.
