Trust me, you do NOT want to be modifying the file system code used on your
live system. Leave your base system running with the release code and use a
virtual machine as your sand box. Actually, use a COPY of a nicely
configured virtual machine. If you mess up, correcting your mistake is a
simple matter of making another copy of the virtual machine. Unless you
enjoy installing/restoring your development machine...
