* RFE?: why no 'bind' info in /proc/mounts?

If I only mount 1 file (or a subdir) via "bind", it still shows the entire
device being mounted on the "bound" directory.

Is there anyway to get a bit more granularity as to *what* was
bound on a name?  (subdir/file..?)

Take a look in /proc/self/mountinfo.  It contains more useful stuff about the
mount table which couldn't be put in /proc/mounts without breaking
compatibility.

 Or use more user friendly findmnt(8) command:


 # mount --bind /usr/local/bin /mnt/test

 # findmnt  /mnt/test
 TARGET    SOURCE                    FSTYPE OPTIONS
 /mnt/test /dev/sda4[/usr/local/bin] ext4   rw,relatime,data=ordered
