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.

Digital UNIX Version 4.0 supports full, cloned, and update installations either from a CD-ROM or across the network from a Remote Installation Services (RIS) server. For more information on RIS, see the guide Sharing Software on a Local Area Network.
Note
The RIS software is available in the Server Extensions kit and requires a separate license and PAK to access. For more information, see Chapter 1 and the Software Product Description for Digital UNIX Version 4.0.
A full installation allows users to install Digital UNIX Version 4.0 on new systems and is divided into the following three procedures:
A default installation installs all mandatory software subsets onto a single disk chosen by the user. Additional optional subsets can be installed later (if there is room on the disk) by using the setld command.
The default installation is intended for those users who do not want to customize their disk partitions, install across multiple disks, and who want to get the operating system up and running quickly and easily.
A custom installation is thoroughly configurable, allowing users to select disks and partitions for the root, usr, and var file systems and for primary and secondary swap. In addition, the custom installation allows users to select from a list of optional software subsets, rather than automatically installing only the mandatory subsets.
The Custom Installation is intended for users who install across different disks and who know which optional subsets they need to install.
A cloned installation lets you duplicate the file system layout, file system type, and software subset selections from a similar type system that has already been installed with Digital UNIX Version 4.0. A cloned installation can only be performed using RIS. If your system is registered to a RIS environment and a configuration description file (CDF) is specified, the installation procedure retrieves the CDF and uses the system configuration information stored in the CDF to configure and install your system.
For more information on full installations, see the Installation Guide.
The Update Installation allows users to update their systems to a new version of the operating system without overwriting customized system files, user files, altering file systems, or destroying existing disk partitions.
Note
Your system must be running Digital UNIX Version 3.2C, 3.2D-1, or 3.2D-2 in order to update install to Digital UNIX Version 4.0.
The installupdate utility invokes the update installation and does the following:
If something new is delivered in a system file that you have customized, or if a system file has changed, the update installation attempts to merge your file with the new file. Although the update installation attempts to merge files automatically, it writes a log of those files that must be merged manually.
Once the update installation is complete, you can load additional subsets using the setld command.
For more information on the update installation, see the Installation Guide and the Update Installation Quick Reference Card.
Once the Digital UNIX Version 4.0 software is installed, if you have graphics capabilities, you can use the SysMan Configuration Checklist to set up your system. The first time you log in as root after a system installation or the first time you log in to a factory installed software (FIS) system, the SysMan Configuration Checklist displays the SysMan applications that are available to set up your system for general use.
Note
When you are logged in as superuser or root, you can invoke the SysMan Configuration Checklist at any time by clicking on the Configuration Checklist icon in the System_Administration folder, or entering the following command on the UNIX command line:
# /usr/sbin/checklist
The following utilities are available from the SysMan Configuration Checklist:
Many of the SysMan Configuration Checklist utilities are also available in text-based interfaces that can be displayed on systems that only have character-cell displays. See Section 13.2.2 for more information.
For more information about system setup in general, see the Installation Guide, the System Administration guide , the Network Configuration guide , the Software License Management guide, and the setup(8) reference page.
