mount with no args should give a list of all mounted devices and their 
options, including bind, but I don't know if it uses mtab or not. The same 
infos are in /proc/mount, but the bind option doesn't seem to appear there. 
The only solution I can see is to check for the device inode (stat -c '%d') 
of all your mount points, looking for duplicate ones, but there's probably 
simpler...
