Comment 8 for bug 1616240

hmm, although priv sep deamon is logging this:

['sudo', 'nova-rootwrap', '/etc/nova/rootwrap.conf', 'privsep-helper', '--config-file', '/nova/nova.conf', '--config-dir', ['/etc/nova'], '--privsep_context', 'vif_plug_ovs.privsep.vif_plug', '--privsep_sock_path', '/tmp/tmpI6Awof/privsep.sock']

That config-dir looks a bit suspect...

that comes from here:
