installupdate(8) System Manager's Manual installupdate(8) NAME installupdate - Invokes the update installation procedure SYNOPSIS /sbin/installupdate [ -i ] [ ris_server: ] /sbin/installupdate [ -i ] [ cdrom_device ] , [cdrom_mount_point] DESCRIPTION The installupdate command invokes the update installation procedure. An update installation updates the DIGITAL UNIX base operating system to the next released version of DIGITAL 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 instal- lation, which is destructive. An update installation does not update optional layered products, but you can still perform an update instal- lation if you have layered products installed. Some layered products operate properly with the new version of DIGITAL UNIX and others must be reinstalled with a version that is compatible with the new version of DIGITAL 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 DIGITAL UNIX CD-ROM distribution media Over a network connection to a Remote Installation Services (RIS) server that is serving the most re- cent version of DIGITAL 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 DIGITAL 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 over- written 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 in- stallation, therefore they are saved with the .PreUPD extension. Rec- tifying lists of obsolete system files. Performing merges of protected system files. These are files that are shipped as part of the DIGITAL 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 func- tionality is merged into the already customized file. Removing obso- lete binary files. Using the setld command to load new software sub- sets. Subsets previously installed are updated as well as any new mandatory subsets that were introduced in the new version of the oper- ating 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 re- spond 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 sav- ing, viewing, or deleting files) on the unprotected customized, obso- lete, and PreMRG files. Unprotected customized files are saved to files with extensions. Other postinstallation tasks may include per- forming 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 Ad- ministration Utility from the SysMan Configuration Checklist. If your system does not have graphics capabilities, invoke the Update Adminis- tration Utility from the /usr/sbin/setup menu. Refer to the Installa- tion Guide for more information about invoking the Update Administra- tion Utility. FLAGS 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.
