Comment 7 for bug 191831

Valient - This is a bug with the FUSE kernel module which is shipped with the kernel, so it should be assigned to the kernel.

It also still exists, so I'm confirming. You might find this useful: http://article.gmane.org/gmane.comp.file-systems.fuse.devel/5789

I discovered this bug because I am testing bindfs. I've created the following bindfs mount in my fstab:

"bindfs#/home/.shared /home/shared fuse owner=root,group=root,mirror=@shared-rw,perms=000:u+rwX:g+rX:o+rX 0 0"

Basically, /home/shared should only be writable by anybody belonging to the group 'shared-rw'. /home/shared should be readable by everybody. However, I find that any user can write to /home/shared, regardless of whether they belong to the group 'shared-rw'.
