     The mmoouunntt__llooffss command makes a sub-tree of an existing filesystem visible
     in another part of the global filesystem namespace.  This allows existing
     files and directories to be accessed using a different pathname.

     The primary differences between a virtual copy of the filesystem and a
     symbolic link are that getcwd(3) functions correctly in the virtual copy,
     and that other filesystems may be mounted on the virtual copy without af-
     fecting the original.  A different device number for the virtual copy is
     returned by stat(2),  but in other respects it is indistinguishable from
     the original.
