I did a find_bind_mount() function as part of: http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=ddf6fb86 I also adjusted df to handle bind mounts better with: http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=0380e4c9 I'll have to revisit these to see if they're still valid. I'll have a look at fixing up df (I guess I'll reverse the mount list and have some internal hash to detect dupes?). I need to see why F15 has started doing this too. For example on my system there are 2 _identical_ entries for /home in /proc/mounts. cheers, Pádraig. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
