Finally, if special is an integer it will be interpreted as the number of
     the file descriptor of an already open fuse device (used when the 
     library invokes mount_fusefs.  (See DAEMON MOUNTS).

I guess the key is ised in conjunction of another software doing any jobs 
over opened fuse device files.

|     mount_fusefs [-A] [-S] [-v] [-D fuse_daemon] [-O daemon_opts]
|                  [-s special] [-m node] [-h] [-V] [-o option ...]
|                  special node [fuse_daemon ...]
|     -s, --special special
|             Use special as special
|So for my case, I can run the mount_fusefs command in two ways:
|- mount_fusefs special node [fuse_daemon ...]
|- mount_fusefs -s special node [fuse_daemon]
|$ mount_fusefs /dev/fuse ~/mnt0 ntfs-3g /dev/da0s1 ~/mnt0
|$ echo $?
|$ mount
|/dev/ada0p4 on / (ufs, local, soft-updates)
|devfs on /dev (devfs, local, multilabel)
|/dev/fuse on /usr/home/user1/mnt0 (fusefs, local, nosuid, synchronous,
|mounted by user1)
|$ mount_fusefs -s /dev/fuse ~/mnt0 ntfs-3g /dev/da0s1 ~/mnt0
|mount_fusefs: special specified inconsistently
|$ echo $?
