Cygwin cannot prevent stupidity.  These "nuked" files should be
recoverable by a restore process from a backup.  However, place your
files that setup doesn't control in other directories and use
/etc/fstab to map them.  For instance I have a c:/opt directory where
I install many applications.  I also have a c:/mnt directory where I
put things like c:/mnt/home and mount that to /home.  I can have two
different instance of Cygwin running with a common $HOME.
