The rules for what mounts are allowed and not allowed varies
considerably depending on kernel version. eg. the latest kernel version
supports mounting the same file system in different places or mounting
multiple file systems to the same point (although only the last file
system mounted can be seen).

So maybe you could make guesses, but if your guess is wrong, and if the
kernel rules are different then expected, the output could be confusing.

The proper fix would be to alter the system call so it can return more
verbose information on what went wrong, but I don't expect to see this
is a hurry....
