- Fixed nbd-client invocation in netboot (bnc #865237)
  nbd has changed it's negotiation style from port based server to
  name based exports. Thus the client has to connect to an export
  name and not a port the server listens to

  Example NBD server config:

    [generic]
      user  = root
      group = root
    [export1]
      exportname = /some/file

  Example NBD localhost test:

    nbd-server -C config-file
    nbd-client -N export1 localhost /dev/nbd0
- DB: update NBD documentation (bnc #865237)
  NBD has changed their negotiation style from port to name based
- DB: rebuild documentation
