Comment 6 for bug 1452205

I installed the Juno release in my lab environment. There is no libreswan driver in it. Finally I create ipsec connection successfully after I replaced
'--ctlbase', '%s.ctl' % self.pid_path
with
'--ctlbase', self.pid_path

I find it keeps the path: '%s.ctl' % self.pid_path in the Kilo release. But I have no environment to test it. However I still have a question about that. If it's the right path, why the '--ctlbase' value in https://github.com/openstack/neutron-vpnaas/blob/master/neutron_vpnaas/services/vpn/device_drivers/ipsec.py#L419 & L443 is self.pid_path. As I know these configs should be the same. Right?
