Software Installation Administrator's Guide

Chapter 5
Using Inst

This chapter describes how to install software using the commands available from the Inst Main menu. It explains how to use Inst commands in each step of a typical installation procedure and what to do after the installation is completed to put the target back into service. After you have performed the procedures in Chapter 3, "Starting a Miniroot Installation" or Chapter 4, "Starting a Live Installation," you can use the instructions in this chapter to complete an installation.

This chapter contains these sections: If you prefer to use a graphical user interface and Software Manager is installed on the target system, you can access Software Manager from the System toolchest and use it to do the installation (for live installations only). See the software installation instructions in the Personal System Administration Guide for help with using Software Manager.

Getting Help During Installations

During an installation session, you can use the help command to get information about almost every command and command argument that appears on Inst menus. Enter the help command alone to get general instructions on using online help. Enter the help command followed by an argument to get help on the topic specified in the argument. Table 9-1 gives a complete list of topics for which help is available.

This sample illustrates a help entry and the information that it provides:
Inst> help upgrade 
                    upgrade U
"upgrade" is a keyword argument for the "install",
"keep", "list", and "step" commands.
For example, "install U" requests that all subsystems that are
currently installed and have newer counterparts in the software distribution be installed...
Understanding installation terminology and the Inst installation model is very important to using Inst successfully. To get this information, issue this command during an installation session:
Inst> help overview 

The Software Installation Procedure

The procedure in this section shows you how to perform a software installation using a particular sequence of commands from the Inst Main menu. The order in which the commands are described is somewhat arbitrary; it illustrates one of many command sequences that might be used to do an installation. As you become familiar with Inst, you can vary the command order, repeat commands, use additional keyword arguments, and issue commands from other menus during installation sessions.

This procedure partitions the installation into seven steps. Each step is explained in the subsections that follow.
  1. Invoke Inst.

  2. Specify the distribution source using the from command.

  3. Display software information using the list commands.

  4. Make your software selections with install, remove, and keep commands.

  5. Launch the installation using the go command.

  6. Resolve any conflicts (conflicts command) or errors.

  7. Quit the installation session.
Note: Inst never installs or removes any software until you enter the go command.

Figure 5-1 illustrates the steps in the installation process. Notice that Inst performs an automatic initialization sequence during the process. Initialization is triggered by the first command of a session that requires Inst to collect information about the distribution or target software. In Figure 5-1 , the trigger is the from command.


Figure 5-1 : Summary of the Installation Procedure

Step 1: Invoking Inst

For miniroot installations, Inst is automatically invoked when the miniroot is loaded (see "Finishing the Miniroot Load" ). For a live installation, Inst is invoked from the command line of an IRIX shell (see "Invoking Inst for Live Installations" ). After Inst is invoked, tit displays the default distribution source and the Main menu, as shown in Figure 5-2 .


Figure 5-2 : The Inst Main Menu

Step 2: Specifying the Source

Perform this step only if you need to change the distribution source from which software will be installed. By default, Inst uses the distribution that was previously specified as the source of installable software for a live installation. For miniroot installations, Inst expects to use the distribution from which you loaded the miniroot. The default source is posted in a message above the Main menu when Inst is invoked. You can either accept the default source or change it using the from command.

Using the from Command

Use the from command to change from one distribution source to another. You can issue the from command to change distributions as many times as you need to during an installation session. Your entry can take one of the forms of from listed below (also see "Alternative Ways to Specify a Distribution" ):

Enter the from command with no arguments to display a selection of former distributions from which to choose; type the number of a selection to specify it as the distribution. If the distribution that you want is not posted, enter an alternate form of the from command to specify the distribution.


Add a pathname argument to from to specify a distribution that is local to the target system (usually a CD-ROM drive). Do not use the tilde (~) in your specification.

These examples illustrate how to specify distributions that are on a local CD-ROM drive and on a local disk directory:
from /CDROM/dist
from /d1/IRIX_5.3/dist

This form of from command also applies to directories and CD-ROM drives that are NFS mounted on the target system.


Add the server name and pathname arguments, separated by a colon, to specify a distribution that is located on a remote system. These examples illustrate how to specify a distribution that is located on a remote directory and remote CD-ROM drive:
from easyboy:/d1/IRIX_5.3/dist
from easyboy:/CDROM/dist

Specify none to display the list of software installed on the target; no distribution is selected in this case. This form of the from command is useful for browsing and removing software from the target system.

Automatic Initialization Functions

Before Inst takes any installation actions, it reads information about the distribution and target. During initialization, Inst obtains historical data about previous installations and reads the product descriptions on the distribution. It also checks for software dependencies among subsystems, makes preliminary installation selections and calculates their sizes, and checks disk availability on the target. As this initialization occurs, you see messages similar to these:
Reading installation history .. 100% Done.
Reading distribution .. 100% Done.
Checking dependencies .. 100% Done.
Calculating sizes .. 100% Done.
When the automatic functions are finished, the Inst> prompt appears, and you can continue with the installation session.

Note: If you do not issue the from command in this step, Inst performs initialization before executing the next command that you enter.

Step 3: Displaying Software Information

Displaying software information is an optional step in the installation procedure. You can omit this step if you are already familiar with the products that you plan to install. In most cases, however, this step is necessary to evaluate distribution and target software and to do progress checks during the selection process.

By default, the list command displays a list of all subsystems in the distribution inventory; but you can also display a complete list of target software using the view command (see "Using the View Commands Menu" for additional ways of using view to control list displays). As you select software for installation or removal (step 4 of this procedure), list displays are automatically updated to reflect your selections.

Using the list Command

Use the list command with no arguments to display the distribution list (if you did not issue the from command in step 2, Inst performs initialization before executing the list command). You can use the names of products and their components, metacharacters, and other keywords as arguments to list commands to save time (see "Using Command Shortcuts" for details).

Example 5-1 illustrates a list entry and the legend that preceeds list displays.
Inst> list 
Current View:
  Location:  distribution
  Status:    N=New,U=Upgrade,P=Patch upgrde,S=Same,D=downgrade,' '=Not Installed
  Patches:   A=patch installable,X=patch uninstallable (missing base product)
  Selection: i=install, r=remove, k=keep
  Level:     subsystem
  Name:      short
  Subsystem Type(s) [bdrp]: b=reBoot needed, d=Default, r=Required, p=Patch]
Example 5-1 : The list Legend

The list legend identifies the location of the software being displayed (distribution in Example 5-1 ), a description of the mnemonic tags that provide information about the software components in the display (listed in the Status, Patches , and Selection lines), the level of the product hierarchy that is displayed (subsystem ), and the sorting order of the displayed products (sorted alphabetically by product shortnames in the example).

Example 5-2 illustrates sample list output of a distribution inventory.
  S bvo.sw.bvo                      0  VGX Broadcast Video Option Software
  S bvo.sw.diag                     0  VGX Broadcast Video Option Diags

Example 5-2 : Sample list Display of Distribution Software

Frequently, list displays comprise several screens of information. To display more information, type <Enter> at the more prompt for a new line and <Space> for a new screen. You can also quit the display before reaching the end by typing q at the more prompt.

Displaying Target Software

Use these commands to change the view and display target software:
Inst> view targ 
Inst> list 
Example 5-3 shows sample list output of target software (the legend is omitted from this display).
  I bvo.sw.bvo                      0 VGX Broadcast Video Option Software
  I bvo.sw.diag                     0 VGX Broadcast Vidio Option Diags
u I compiler_eoe.sw.cpp [bdr]       0  Source Code Preprocessor

  R showcase.sw.showcase [d]        0  IRIS Showcase 3.3 Software
Example 5-3 : Sample list of Target Software

Use this command to return the view to the distribution:
Inst> view dist 

Interpreting list Output

A list display contains several columns of information about each software component in the display. Some columns convey information by means of mnemonic tags, which are defined in the list legend (see Example 5-1 ). Columns appear empty when a tag is unassigned or when the tag is masked by the current view setting (see "Using the View Commands Menu" for more information).

The columns in list displays contain this information:
Column 1

A pending selection on the software component, if a selection was made. This column may contain any item listed in the Selection line of the list legend.

Column 2

The status of the software component relative to its corresponding component on the target or distribution. This column contains an item listed in the Status line of the list legend.

Column 3

The name of the software component. When software subsystems are displayed, the name may be followed by one or more special designations from the Subsystem Type line of the list legend (see Example 5-1 ).

Column 4

For software items being installed (i) or removed (r), a comparison between the disk space requirements of the distribution and target versions of the software. The amount, which is displayed in kilobytes by default, is followed by a plus sign if additional space is required or a minus sign if space is freed. If items are not selected for installation or removal or if there is no net change, the size shown is zero.

Column 5

A brief description of the software component. The content of this description varies slightly with each product.
These items from Example 5-2 further illustrate the information provided about distribution software by the list command:
S bvo.sw.bvo

The distribution version of the bvo.sw.bvo subsystem is the same (S) as the version on the target; no action is to be taken on this subsystem (the first column is blank).

i U compiler_eoe.sw.cpp [bdr]

The distribution version of compiler_eoe.sw.cpp is an upgrade (U) to the version that is currently on the target. This subsystem is selected for installation (i). Installing compiler_eoe.sw.cpp requires a reboot (b) of the target; the manufacturer has selected this subsystem as a default (d) for installation; compiler_eoe.sw.cpp is required (r) for system operation.

i U compiler_eoe.sw.unix...26-

The distribution version of compiler_eoe.sw.unix is an upgrade (U) to the version that is currently on the target. This subsystem is selected for installation (i); the distribution version is 26 kilobytes smaller than the corresponding version on the target.

D [d]

The subsystem in the distribution is a downgrade (D) of the corresponding subsystem on the target. Since the target version of this subsystem is newer, no action is to be taken on this subsystem, even though the manufacturer recommends it as a default (d) installation selection.
The information in Example 5-3 indicates that most products from the distribution are currently installed (I) on the target, but the showcase subsystems have been removed (R). One distribution product from Example 5-2 , onc3_eoe, does not appear in the target list in Example 5-3 . Also notice that items marked for installation (i) in the distribution list are marked for upgrading (u) in the target list.

Interpreting Patch Information

A list display also includes patch components if patches are present on the distribution or target. Example 5-4 illustrates patch entries in a list display.
DA patchSG0000000.eoe1_sw.unix [bp]    0  IRIX Execution Environment
SA patchSG0000001.eoe1_sw.unix [bp]    0  IRIX Execution Environment
PA patchSG0000002.eoe1_sw.unix [bp]    0  IRIX Execution Environment
NA patchSG0000005.4DDN_sw.4DDN [bd]    0  4DDN Software
NX patchSG0000011.dwb_sw.aps [p]       0  Autologic APS-5 Fonts
Example 5-4 : Sample list of Patches

The mnemonic tags on patches have these meanings:
(Downgrade Available) This patch applies to an installed base subsystem; it is a downgrade to another patch that is already installed.

(New Available) This patch applies to a base subsystem that is installed or available for installation; it does not apply to any installed patch.

(New Uninstallable) This patch applies to software that is not installed and not available for installation from this distribution.

(Patch Upgrade) This patch upgrades installed software.

(Same Available) This patch is already installed.

Interpreting the Disk Space Summary

At the end of each listing, the list command posts a disk space summary similar to those shown in Example 5-5 (summary from a live installation session) and Example 5-6 (summary from a miniroot installation). The summary identifies the target filesystems to receive the selected software, estimates the additional space (or space savings) that will result if the selected software is installed, and displays the amount of space available on the target filesystems.
Disk Space summary (Kbytes)         / 
Selections net change            1276+
Space available                564432
Example 5-5 : Sample Disk Space Summary for Live Installations
Disk Space summary (Kbytes)   /     /root     /root/usr
Selections net change         0         2+         149+
Space available           11984      6062       216876
Example 5-6 : Sample Disk Space Summary for Miniroot Installations

Step 4: Making Software Selections

Three types of actions can occur on a target during an installation: Distribution software is installed, target software is removed, and some target software is kept in its present condition. In this step, you specify which of these actions should be taken against selected software when the installation is performed (step 5 of this procedure). The install, remove, and keep commands select software for the designated action.

In most cases, the selection step is needed to adjust software for the capacity of the target and the needs of its users. However, in some cases it is possible to accept the automatic selections that Inst made during initialization. These selections are described in "Accepting Automatic Selections" .

Note: If the automatic selections described on page 62 are suitable for your circumstances, you can accept these selections and go directly to step 5 of this procedure.

Using install, remove, and keep Commands

The install, remove, and keep commands select software products and their components for a particular action. No action is taken until you issue the go command (see "Step 5: Launching the Installation" ), so you can change your selections as many times as necessary before entering go.

Note: You can use the step command to display items on the distribution individually and make your selections as each item is displayed. See "Using step to Make Selections" for details.

When you make your selections, keep these points in mind:

Simple Selection Command Entries

In their simplest form, the install, remove, and keep commands contain one argument that identifies the product, image, or subsystem on which the action will be taken. If you specify a product or image as the argument to install, remove, or keep commands, the action is taken on all subsystems of the product or image.

These sample entries explain the effects of selection command entries:
Inst> install sysmon

Install all parts of the product sysmon, which is either a new product for the target or an upgrade to the installed version.

Inst>remove InPerson.books

Remove the currently installed InPerson.books image from the target.

Inst>keep DeltaCC.sw.backend

Retain the DeltaCC.sw.backend subsystem (if it is installed) or prevent installation of the distribution version.
You can use multiple arguments in install, remove, or keep commands, as shown in Example 5-7 . Your arguments can extend to new lines, as long as the last character on the line is not an empty space.
Inst> install sysmon cadmin mmail
Inst> keep InPerson.books InPerson.sw 
Inst> remove DeltaCC.sw.backend
Example 5-7 : Multiple Arguments to install, remove, and keep

Using Arguments in Selection Commands

You can use the names of products and their components, metacharacters, and keywords as arguments to install, remove, and keep commands to save time (see "Using Command Shortcuts" for more information). These sample entries illustrate the use of keywords in selection commands:
Inst> install required

Install all subsystems that are required for optimum system operation.


Remove all images with a .man extension from the target.


Keep all eoe1 subsystems that are currently installed on the target (do not install upgrade versions from the distribution).

Checking Your Selections With list

You can issue a list command during the selection process whenever the Inst> prompt is displayed. The first column of the listing and the disk space summary information reflects your selections and their effects on disk space.

Accepting Automatic Selections

Recall from step 3 that Inst automatically made some preliminary selections during initialization (also see "Automatic Initialization Functions" ). If you accept the automatic selections, you can omit step 4 and go on to "Step 5: Launching the Installation" .

Use this command to display the list of software that is selected for installation:
Inst> list i  
Example 5-8 illustrates a portion of the display that was generated by the previous list command. Notice that the display concludes with an estimate of space requirements, which may help you decide whether to accept the automatic selections.
i  U eoe1.sw.gfx_lib bdr      19+   Graphics Execution Libraries
i  U eoe1.sw.irix_lib bdr     991-  IRIX Execution Libraries
i  U eoe1.sw.unix bdr         6674- IRIX Execution Environment
i  U eoe2.sw.cdrom d          241-  CD-ROM Support
i  U eoe2.sw.crypt d          25-   Security Administration Utilities
i  U eoe2.sw.gltools d        80-   Graphics Library Tools
Disk space summary (Kbytes):           /
Selections net change              64793-
Space available                   538102
Example 5-8 : List of Subsystems Selected for Installation

Step 5: Launching the Installation

The selections that you made in step 4 are processed when you launch the installation with the go command. The order in which you made selections in step 4 has no effect on the order in which they are processed. You can process any number of selections: it is not necessary to complete all your selections before you enter go.

Note: Inst will detect a conflict condition if you fail to include any prerequisite software in a selected subset (see "Step 6: Resolving Conflicts and Other Errors" for details).

As the go command executes, Inst determines whether your selections contain incompatibilities, missing prerequisites, space shortages, or other errors that might make the new software configuration unsuitable for the target. To keep you informed of events, Inst posts status messages during go processing.
Inst> go
Pre-installation check ..  100% Done.
Installing/removing software .. 0%
Installing new versions of selected subsystems
Installing/removing software .. 44%
Installing new versions of selected pv.sw subsystems
Installing/removing software .. 100% Done.
Removing orphaned directories 
Running exit commands .. 100% Done.
Checking dependencies .. 100% Done.
Installations and removals were successful.
You may continue with installations or quit now.
Example 5-9 : Successful Installation Messages

Notice that Example 5-9 contains a success message:
Installations and removals were successful
When you see this message, you can either continue the installation session or go directly to "Step 7: Quitting the Installation Session" . If you receive an error message instead of a success message, complete "Step 6: Resolving Conflicts and Other Errors" before going on to step 7.

Step 6: Resolving Conflicts and Other Errors

The installations and removals that you specified in step 4 are not performed if conflicts or error conditions are detected during go processing. Conflicts occur if you select software that depends on prerequisites that you did not select, or if a selection is incompatible with other selections or with installed software. Other errors that occur during go command processing are resolved with routine corrective actions (see Appendix A, "Installation Troubleshooting," for additional error-handling information).

Using the conflicts Command

If Inst detects a conflict in the software that you selected, it posts a conflicts message after you enter the go command. Conflict error messages are followed by a description of the conflicts and recommended actions that you can safely perform to resolve the conflicts. You use the conflicts command to select a suggested resolution. You can also issue the conflicts command periodically during the selection process to display any conflicts that might be accumulating as a result of your selections.

Example 5-10 illustrates a message describing two conflicts.
ERROR: Conflicts must be resolved.
Movie Playback, Recording, Conversion cannot be installed because of missing
prerequisites: 1a. Do not install Movie Playback, Recording, Conversion 1b. Also install Compression Execution Environment eoe1.sw.dlpi (DLPI Execution Environment),
eoe1.sw.dlpi (DLPI Execution Environment) and
eoe1.sw.dlpi (DLPI Execution Environment) cannot be removed because other products depend on them: 2a. Do not remove eoe1.sw.dlpi (DLPI Execution Environment),
eoe1.sw.dlpi (DLPI Execution Environment) and eoe1.sw.dlpi
(DLPI Execution Environment) 2b. Also remove 4DDN.sw.4DDN (4DDN Software)
Example 5-10 : Sample Conflicts Message

To resolve a conflict, enter the conflicts command and your choice of resolutions as command arguments, as shown in Example 5-11 .
Inst> conflicts 1b 2a 
Example 5-11 : Sample Entry to Resolve Conflicts

When you have successfully resolved all conflicts, Inst posts a success message. Enter the go command after the message to process any new selections.
No conflicts
Inst> go 
If the go command returns a success message (see Example 5-9 ), you can continue with the session or go on to "Step 7: Quitting the Installation Session" .

Correcting Other Installation Errors

If Inst is unable to execute the go command for reasons other than conflicts, it posts error messages that suggest the cause of the error and presents choices for your next action. Errors can occur during pre-installation checking, while software is being installed and removed, or during exit operations.

Example 5-12 illustrates an error that occurs during pre-installation checking.
Inst> go 
nfs-mounted filesystem /usr/local/bin/ptools is read-only
nfs-mounted directory /usr/local/bin/ptools/app-defaults is write-protected
nfs-mounted directory /usr/local/bin/ptools is write-protected
Installations and removals canceled
Example 5-12 : Sample Error in Pre-Installation Processing

Most error messages contain information that suggests the corrective action that is required; however, if you need additional information to correct an error, see Appendix A, "Installation Troubleshooting."

Example 5-13 illustrates an error that occurs during installation processing.
Inst> go 
Pre-installation check
Installing/removing software
Upgrading selected subsystems
Installing new versions of selected prod1.sw subsystems
ERROR : An error occurred while Installing new versions of selected prod1.sw

Example 5-13 :
Sample Error in Installation Processing

Notice from Example 5-13 that if you encounter errors during installation, Inst invokes the Interrupt menu (explained in "Using the Interrupt Menu" ). This version of the Interrupt menu includes a "retry" choice, which might be used, for example, if the error is caused by a network timeout. If you need additional information to correct the error, see Appendix A, "Installation Troubleshooting."

Example 5-14 illustrates an error that occurs during exit operations.
ERROR : Sub-command "cd $rbase/usr/lib/filetype; ./tagscript $rbase;
rm tagscript" returned status 1 100% Done. Errors occurred executing exit-ops
Example 5-14 : Sample Error in Exit Operations

See Appendix A, "Installation Troubleshooting" for an explanation of messages that are generated during exit operations.

Step 7: Quitting the Installation Session

You can leave an installation session at any time by issuing the quit command at the Inst prompt. If any installation or removal selections are pending, Inst notifies you:
Inst> quit 
There are products marked for installation or removal.
Do you really want to quit?(y/n)
If you enter y, the session ends and your pending selections are not processed. Enter n if you decide to continue the session.

If the installation installed a new icon in the icon database, you see the message:
The Icon Database is being updated. Desktop icons may disappear for a moment.
The icons disappear and then reappear after about five seconds.

Handling Unresolved Conflicts

In some cases, there may be unresolved conflicts when you issue the quit command to end a session. For example, unresolved conflicts occur when you try to end a session without installing all software that is required for an operating system upgrade.

If there are unresolved conflicts when you issue the quit command, Inst posts this message:
Some software that was already installed on your system prior to this 
session is incompatible with the new software. The conflict messages above
(or below) list the incompatible software. You can either:
- Insert another CD or specify another distribution directory that contains
  compatible versions of software (for example, if you are in the middle 
  of an operating system upgrade, insert the next CD that you received 
  with the upgrade), then start the installation.
- Remove the incompatible software by making conflict resolution choices
  as shown above (or below).
Example 5-15 : Conflicts Message When Quitting Inst

This message is followed by a list of conflicts that must be resolved before you can end the session successfully. See "Step 6: Resolving Conflicts and Other Errors" for information on conflict resolution.

Note: If you set the rulesoverride preference on (not recommended), the conflicts message varies from the one shown in Example 5-15 . With rulesoverride on, the message identifies the unresolved conflicts and warns you that the installation will be performed despite remaining conflicts.

If Rebooting Is Needed

If you install products that require a system reboot to put the software into effect, you see the message in Example 5-16 .
Installations and removals were successful
You must reboot your system to complete the installation.
Example 5-16 : Quit Prompt With the Reboot Message

After you reboot the system, you see this message:
Requickstarting necessary files

The Requickstart Sequence

During exit processing, Inst synchronizes the libraries and executable files in the new installation that rely on shared objects. This process is known as a requickstart; it ensures a faster startup time for the affected files. If this is the first time that you installed products that require a quickstart, you see the message shown in Example 5-17 .
1. Continue with the session
2. Quit now
Please enter a choice [1]: 2 
Building a one time quickstart data file
Requickstarting necessary files
Automatically reconfiguring the system.
Ready to restart the system. Restart? (y)es,(n)o,(sh)ell,(h)elp}:
Example 5-17 : Quit Prompt With a Quickstart File Message

For some installations, the requickstart might require as long as 20 minutes; however, for most installations, much less time is required. During the requickstart, you might see informational messages similar to this:
Building dynamic ELF inventory file for rqs(1) processing .. 100% Done.
Invoking rqs(1) in necessary dynamic ELF objects .. 100% Done.

Stopping the Remote CD Manager

If your distribution source was a CD on a remote installation server, cdinstmgr is still running on the installation server (see "Preparing the Remote CD-ROM Drive" ). Follow this procedure to stop cdinstmgr:
  1. Go to the remote server or use a remote login.

  2. Type "quit" at the prompt.

    This prompt is posted until you stop cdinstmgr (see "Preparing the Remote CD-ROM Drive" ):
    CD on CDdir for host hostname: type the word 
    "done" when you are finished with this CD, "quit"
    if you are completely done: quit

  3. You might see this message from cdinstmgr:
    CD on CDdir for host hostname: the CD-ROM daemon was 
    started by you,leave it running? (y/n)
    If you answer yes, the CD is not ejected and cdromd(1M), which was started by cdinstmgr, is not stopped. If you answer no, cdinstmgr attempts to eject the CD and stop cdromd. If the CD is in use, this message is displayed and the CD is ejected:
    CDdir: Device or resource busy

  4. Eject the CD, if you wish.

    To eject the CD, issue the eject(1) command at the installation server or from the remote login session.
    % eject
    If the CD is in use, this command fails and the CD
    is not ejected.

Managing Configuration Files

Sometimes a distribution contains configuration files, which are either required or recommended for operation, that exist on the target in a modified form (an /etc/passwd file, for example). When the target system contains modified configuration files, Inst preserves the modified files during the installation in one of two ways:

The Configuration File Notice

When a new version of a configuration file is created during an installation, Inst posts a message about the changed files after go processing is completed. The message, shown in Example 5-18 , is repeated the next several times that the target system is rebooted.
Software installation has installed new configuration files

to update or merge old configuration files with the newer

Merging Configuration Files

To avoid compatibility problems, plan to merge configuration files if new versions were created. Use this procedure to merge configuration files:
  1. Identify changed configuration files with this command:
    # showfiles -cCH 
    Example 5-19 illustrates output of the previous showfiles command.
    Configuration Files
    m     = modified since initial installation
    ?     = modification unknown
    blank = file is as originally installed
    ? /etc/halt.O 
    m /etc/passwd
    ? /etc/reboot.O
    m /etc/services
    ? /usr/etc/inetd.conf.O
    Example 5-19 : Listing of Changed Configuration Files

    The .O versions of the configuration files are the earlier versions. In this case, the no-suffix version contains changes that are required for compatibility with the rest of the newly installed software, that increase functioning, or that fix bugs.

    The .N versions of the configuration files are the versions created during the installation. They contain changes or new features that can be added to the no-suffix version of the configuration file at your option.

    Note: The release notes might have information about the changes that were made to configuration files in the new release.

  2. Merge information from both versions of the configuration files.

    Use diff or xdiff to compare .O and .N files with their no-suffix counterparts. Transfer information that is needed from the .O version to the no-suffix version. Add information from the .N version to the no-suffix version if you want it.

  3. Delete the .O and .N versions of the configuration files.

    If you want to keep .O and .N files, rename them, since they might be removed automatically during the next installation. When you remove all .O and .N configuration files, no message about configuration files appears when you reboot the system, and the startup process is faster.

If Inst Is Interrupted

If an installation session is interrupted by an abnormal event (such as a power failure), Inst saves a record of pending requests for product installations and removals in a checkpoint restart file. At the start of the next session, Inst posts a checkpoint restart notice that identifies the software distribution and lists the products on which actions are pending.

Completing a Checkpoint Restart

This checkpoint restart message is displayed if an installation session is interrupted abnormally:

To proceed, choose one of the restart selections from this prompt. Checkpoint restart selections have these effects:

If a Checkpoint Restart Fails

Failures during a checkpoint restarts are frequently caused by four conditions, which are usually easily corrected:
