Comment 1 for bug 1158681

The bug comes after change done in the common nfs at cinder.volume.drivers.nfs.py in the class NfsDriver. The change replaced Flags with oslo configuration. To read option nfs_mount_options, Flag is replaced by cfg.CONF. I am not clear why is it done this way, is it to place option nfs_mount_options as a common option ? in that case it needs to be present in the common options at cfg.CONF. Or if thats not the case then is it required to be specified in conder.conf while configuring, this will require change in NfsDriver as well. Mentioning the change number for the author to reply on this. This causes dependent nfs drivers to fail mounting nfs exports.
