Overview

Digital UNIX Version 4.0 supports full, custom, and cloned installations for new systems and an update installation that allows users who already have Version 3.2C, 3.2D-1, or 3.2D-2 of the operating system installed to update to Digital UNIX Version 4.0 without overwriting system files. Also, Digital UNIX Version 4.0 supports a variety of setup utilities that allow users to configure their systems quickly and with relative ease.

Both the installation and setup utilities use a graphical user interface (GUI) on systems that support graphics and a text-based interface on systems that do not.

Additionally, the CD-ROM used to install Digital UNIX Version 4.0 contains file systems that are laid out just as the software would be installed on the system. It has directly accessible root, /usr, and /var areas. This format makes almost every operating system command and utility available to the installation process because your system actually mounts the installation media and runs off of it during the installation. You therefore have access to a complete, albeit generic, Digital UNIX operating system during the installation itself. This means that the UNIX commands required for recovery procedures, such as restoring corrupt file systems, are readily available even if your operating system is not yet fully functional. Also, if you inadvertently delete a system file, you have easy access to the file on the CD-ROM. The RIS area from which you invoke an installation is laid out in the same format as the CD-ROM and provides the same advantages.
