neutron team would like to collect some more data about network setup
for nodes into sos-report. Particularly, we would like to get a
snapshot of all bridges and other devices set on a node, using
plotnetcfg . The tool produces a dot file  that allows to get a
graphical represantation of network devices on a system, that can then
be used to determine whether it's sane.
We already have a sos-report patch  in review that is scheduled for
OSP7 (thanks Lee!). We've also imported the plotnetcfg package into OSP7.
I think the best way to make sure the package is installed on all nodes without adding a hard dependency for neutron (which is technically wrong) is to add the package to the list of those installed by default by Director.
