/bin/sbin/usr/bin/usr/sbin This is the placement directory for the system preset execution file
/usr/local This is the system preset to let you install your later Upgrade kit directory
/home This is where the system will have the username of the person who set up the house directory
/var www ftp db mail logmessages etc.
/usr/share/man/usr/local/man These two directories are places where you place the documentation for each type of kit
