How do I UNMOUNT '/' mount point?

What exactly are you trying to do?  Is it something like you have a C:\root
directory that you want the / to point to?  That is possible.  Just do:

cd <dir/to/bin> && ./umount / && ./mount 'c:\root' /

If you want something different then you have the source to change it to suit
your needs.
