Igor, thank you for your reply.
I also tried to use the file descriptor number as an argument for the
$ ls -ali /dev/fuse
57 crw-rw-rw- 1 root operator 0x39 21 мая 11:40 /dev/fuse
$ mount_fusefs -s 57 ~/mnt0 ntfs-3g /dev/da0s1 ~/mnt0
mount_fusefs: special specified inconsistently
$ echo $?
My question is why "mount_fusefs /dev/fuse ..." works and "mount_fusefs
-s /dev/fuse ..." and "mount_fusefs -s 57" do not work.
