 There is no difference. The "bind" is an operation, not a special
 state of any mountpoint. Nowhere in the system is information that
 the mountpoint has been created by "bind" -- the kernel does not
 see any difference between the original and bind mount. It's just
 another reference to the same object (device).

    mount /dev/sda1 /mnt1
    mount /dev/sda1 /mnt2

 is exactly the same as:

    mount /dev/sda1 /mnt1
    mount --bind /mnt1 /mnt2


 We should not care about "bind" flag in mtab (or another place) at
 all. The solution is to de-duplicate df(1) output.


 It's fine to blame systemd guys for all the bad things in the World,
 but kill the original mtab concept was planned independently on
 systemd.
