test cases : tests/basic/quota_aux_mount.t and other quota TC have been failing on netBSD:

>>> from code we have 
  fuse_thread_proc()
  ....
  res = sys_readv (priv->fd, iov_in, 2);
  if (res < sizeof (finh)) {
           gf_log ("glusterfs-fuse", GF_LOG_WARNING,
                   "short read on /dev/fuse");

  }
Will need to investigate further from  fuse +_NetBSD perspective
