F15: ugly behavior of "df"

what triggers that since F15 every bind-mount is displayed in
"df" with "ext4" and the full volume-szize and additionally
if BIND is running in a chroot FOUR volumes with the size
of the root-fs are shown and a normal user gets "access denied"?

this is way too much for 3 physical volumes!
