Thanks, here is what I've got so far: it seems /dev/fuse[0-9]* devices
aren't removed after the corresponding filesystem is unmounted (I guess
they are reused), so instead of listing /dev the list has to be taken
from 'mount'. Also there should be a delay between the 'umount' and
'kldunload' commands. What do you think about the following
(replacement for fusefs_stop function)?

echo "Stopping ${name}."
for fs in `mount | grep '^/dev/fuse[0-9]*' | cut -d ' ' -f 1`; do
	umount $fs
done
sleep 2
kldunload $kmod

Unfortunately it doesn't have a status function to avoid loading when
already loaded and the other way, but can easily be added.

Best Regards,
Ale
