Bug description:
[Impact]
Fix for bug 1818614 in *-proposed includes a regression is the deployment is
not using the rootwrap-daemon.
[Test Case]
See bug 1818614
[Regression Potential]
Low - this is a minor fix to resolve a regression due to the SRU bug 1818614.
[Original Description]
As fix for bug https://bugs.launchpad.net/neutron/+bug/1818614 we
added to neutron-keepalived-state-change monitor possibility to check
initial status of router (master or slave).
Unfortunately for some reason I see now in journal log of functional
job that this check is failing with error like:
