installupdate - Invokes the update installation procedure
/sbin/installupdate [ -i ] [ ris_server: ]
[ -i ] [ cdrom_device ] ,
The installupdate command invokes the update installation procedure. An update installation updates the Tru64 UNIX base operating system to the next released version of Tru64 UNIX . The update installation preserves user files, data files, print and network configurations, user accounts, and any other system setup and customization you may have done. Preserving this data is an advantage over the full installation, which is destructive. An update installation does not update optional layered products, but you can still perform an update installation if you have layered products installed. Some layered products operate properly with the new version of Tru64 UNIX and others must be reinstalled with a version that is compatible with the new version of Tru64 UNIX . Some layered products, such as DECnet, must be deleted before the update begins and then reinstalled after the update completes.
There are two distribution methods for an update installation: From the Tru64 UNIX CD-ROM distribution media Over a network connection to a Remote Installation Services (RIS) server that is serving the most recent version of Tru64 UNIX
The update installation is performed from single-user mode. You must be superuser or the user root to bring a system down to single-user mode.
Whether you are using CD-ROM or RIS, the update installation process is started by entering the /sbin/installupdate command from the command line.
The functions performed by installupdate during the update installation process include: Detecting and logging obsolete system files - files that were previously shipped with Tru64 UNIX but are not in the new release. Detecting and logging unprotected customized files - files that have changed since the previous installation that will be overwritten during the update installation. Saving unprotected customized files to .file.PreUPD to preserve custom versions. These files are not expected to be modified and are not merge protected from the update installation, therefore they are saved with the .PreUPD extension. Rectifying lists of obsolete system files. Performing merges of protected system files. These are files that are shipped as part of the Tru64 UNIX operating system and Digital expects user to customize them (for example, the /etc/hosts file). These files are merge protected which means that user customizations are preserved and newly introduced functionality is merged into the already customized file. Removing obsolete binary files. Using the setld command to load new software subsets. Subsets previously installed are updated as well as any new mandatory subsets that were introduced in the new version of the operating system. Performing software subset configuration. Building a custom kernel and rebooting the system with that kernel.
An update installation completes in 90 to 150 minutes from CD-ROM and in 90 to 150 minutes from RIS. Actual time varies depending on your processor type, the number of software subsets that have to be updated, network traffic, and the speed of the CD-ROM device. You need to respond to prompts only during the initial phase of the update.
When you are satisfied that your system is working as expected, use the Update Administration Utility to perform management tasks (such as saving, viewing, or deleting files) on the unprotected customized, obsolete, and PreMRG files. Unprotected customized files are saved to files with .PreUPD extensions. Other postinstallation tasks may include performing manual merges for those that were not done automatically and rebuilding the kernel with layered product special options.
If you system has graphics capabilities, you can invoke the Update Administration Utility from the SysMan Configuration Checklist. If your system does not have graphics capabilities, invoke the Update Administration Utility from the /usr/sbin/setup menu. Refer to the Installation Guide for more information about invoking the Update Administration Utility.
Invokes an interactive kernel build that lets you select kernel options from the kernel options menu and then edit the configuration file to recreate any kernel customizations you may have previously made in the file.
