Optional Package Components

Package Information Files

There are four optional package information files you can include in your package:

• The compver file

  Defines previous versions of the package that are compatible with this version.

• The depend file

  Indicates other packages with which this package has special relationships.

• The space file

  Defines disk space requirements for the target environment, beyond what is needed by the objects defined in the prototype file. For example, additional space might be needed for files that are dynamically created at installation time.

• The copyright file

  Defines the text for a copyright message displayed at the time of package installation.

Each package information file should have an entry in the prototype file. See "Creating Information Files" for more information on creating these files.

Package Installation Scripts

Installation scripts are not required. However, you can provide scripts that perform customized actions during the installation of your package. An installation script has the following characteristics.

• It is composed of Bourne shell commands.

• Its file permissions should be set to 0644.

• It does not need to contain the shell identifier (#! /bin/sh).

The four script types are as follows:

• The request script

  The request script requests input from the administrator installing the package.

• The checkinstall script

  The checkinstall script performs special file system verification.

  Note -

  The checkinstall script is only available with the Solaris^TM 2.5 and compatible releases.

• Procedure scripts

  Procedure scripts define actions that occur at particular points during package installation and removal. There are four procedure scripts you can create with these predefined names: preinstall, postinstall, preremove, and postremove.

• Class Action scripts

  Class Action scripts define a set of actions to be performed on a group of objects.

See "Creating Installation Scripts" for a more information on installation scripts.
