What I tried is to mount ODL mdsal netconf server (port 1830) as a mount point,
specifying a schema folder containing the YANGs. The mount succeed, but
interaction with the mount point doesn’t work at all, throwing
java.lang.IllegalArgumentException: No

I did not dig up on this error, this is more an FYI as hack I tried.
