Bind mounts are like hard links... there is no such thing as "this is the original one versus this is the bind mount"; the only difference between the file and the hard link, or between the mount and the bind, is which was created first. In that sense, trying to pick out which is the bind mount isn't merely futile, it is actively wrong. This is especially so since it is perfectly legitimate to remove the original mount leaving only the "bind" mount in place(*). -hpa (*) this is, in fact, the only way under Linux to mount a volume subdirectory as at a mount point. -- H.
