is there a problem with bind mount handling? Yes Was it caught in
testing? Seems like it wasn't. Does Fedora make any effort to test
bind mounts as part of organized pre-release QA? I'm not aware that we
do as our pre-release QA is quite narrowly scoped to ensure default
install configs as we don't have the resources to test all possible
configurations and command options.
* bind-chroot-9.8.0-7.P4.fc15.x86_64 is a untouched fedora-package
* so fedora is ACTIVE creating bind-mounts
* /bin/df is a core utility and throws error
* /bin/mount is a core utility
* /bin/mount has NO information about a bind-mount
so if "/proc/mounts" is the kernel-layer why do it not
contain any hint what is a physical device and hwat
are bind-mounts? in other words: HOW get the information?
from my point of view i would have no idea how anybody should
fix /bin/df or /bin/mount if /proc/mounts has no informations
for the userland what is going on on the system

the permanently raising number of all sorts of "tmpfs" makes the output of
"df"
also not better readable and their size of 4GB on a machine with 8GB
pyhiscal memory makes my look also critical
