This issue happens on Debian where package fuse3 provides both fusermount3 and fusermount.

In FUSE 3, nonempty is always true, and has been removed. By default it is false on FUSE 2.

Seems later fusermount versions removed the option, I added a commit to remove the option for linux.

This is still not fixed. I've just attempted to mount but it fails even on 1.67:

$ ./weed mount -dir=/mnt/weed -filer=192.168.0.5:8888 -dataCenter=dc1
I0322 11:39:40  2565 config.go:30] Reading : Config File "security" Not Found in "[/var/tmp/weed /home/{USER}/.seaweedfs /etc/seaweedfs]"

Please reopen.

Add a fix to make nonempty optional.
