commit 50b3a168e86316ab92ba828c1a00ab963532ad1c Author: Matt Riedemann <mriedem...@gmail.com> Date: Thu May 31 17:41:27 2018 -0400 Mention neutron-rootwrap-daemon in root_helper_daemon option help An operators mailing list thread [1] discussing scale issues where vif plugging times out eventually came to the conclusion that several operators run rootwrap in the neutron agent in daemon mode. This ability is not clear from the configuration option help, however, so this change adds more details on running in this mode to achieve scale. Another nice discussion about this can be found here [2]. There is a corresponding nova patch [3] to mention this option if operators are hitting vif plugging timeouts in nova. This doesn't change any defaults, it just improves the documentation. The help text formatting is also updated for easier readability and maintainability in the source.
