Repeating my comment from the change in question:

I'd like to see all rootwrap filters with a command path prefix of /usr/local/bin removed and devstack updated to rewrite exec_dirs of the deployed rootwrap.conf in the same way we already update filters_path:

https://github.com/openstack-dev/devstack/blob/master/lib/neutron-legacy#L1147

So something like the following

 sudo sed -e 's:^exec_dirs=\(.*\)$:exec_dirs=\1,/usr/local/bin:' $Q_RR_CONF_FILE
