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 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.

FLAGS
  -i  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.
