Link from ovs config file to plugin.ini on RedHat

michaeltchapman · Chris Hoge · commit d7ea12e36542 · 2014-07-03T17:45:38.000Z
All init scripts for neutron-openvswitch-agent from RedHat packages use the non-ml2 config file path. When using ML2 this causes problems since all config is set under the ML2 plugin directory. Since this is only a bug when using ML2, but not when using the monolithic plugin, it may not be fixed in packages. https://bugzilla.redhat.com/show_bug.cgi?id=1087647 This patch creates a symlink from the old plugin config path to the new one to mitigate the issue. Change-Id: I5feb8fc39fa4d67aebb4209d7b44bea38d1a9d5f (cherry picked from commit a28f734)
