bindfs works, but not via /etc/fstab

Question

I can do a bind mount like this:

bindfs -u target --mirror=target /home/source/import/target /home/target
umount /home/target

But it fails, if I try to do the same thing via /etc/fstab:

# fstab line:
/home/source/import/target /home/target  fuse.bindfs  mirror=target 0    0

Try to mount via /etc/fstab:

LANG=C mount /home/target

mount: wrong fs type, bad option, bad superblock on /home/source/import/target,
   missing codepage or helper program, or other error

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

But dmesg does not contain a new entry.

target and source are the name of directories and the name of two linux users.

What is wrong?

Hints how to debug this are welcome.

Alternative solutions are welcome, too. All I want is that new files created by user target in /home/target are visible for user source in /home/source/import/target.

Did you try the deprecated syntax for fstab entries as found in man bindfs?

# fstab line:
bindfs#/home/source/import/target /home/target  fuse  mirror=target 0    0

I tried your line, but it was the same. I found the answer: The RPM fuse was missing. – guettli Apr 18 '19 at 12:10

One day later I found the solution myself.

The RPM fuse package was not installed. Mounting via /etc/fstab seems to need it.

Mounting on the command line seems to not need it.

Now it works fine.
