In order to make sure that your software is installed correctly, PackageMaker allows scripts to customize the installation behavior.
JavaScript can be used to create a distribution script to customize the installation experience. Specific shell scripts can be used in a package to carry out commands before and after the package is installed. Installer distribution scripts are new in Mac OS X v This feature allows you to define the user experience within Installer using a single configuration file.
You store this file in either a. You can also take a metapackage and convert it to a distribution script. Use distribution scripts to do the following:. You can now consolidate many of the flags and functions configured by PackageMaker and the included shell scripts such as InstallationCheck and VolumeCheck into a single distribution script.
The entire range of flags and standard package scripts, plus new features of Installer, are configured using JavaScript within that one file. Distribution scripts are used only by Mac OS X v They are ignored by Mac OS X v Scripts are an optional element of an installation package.
You add scripts when you need to test certain conditions before installation or when you need to perform special tasks as the installation takes place. You can define two types of scripts: environment-test scripts and installation scripts. Environment-test scripts include the following:. InstallationCheck— Installer runs this shell script early in the installation process to determine whether the installation should proceed.
If the installation cannot proceed, Installer displays a localizable message to the user. Supply this file to check for criteria such as minimum hardware requirements.
If the installation cannot be done on a volume, Installer communicates this fact to the user, again using a localizable message. Supply this file to check for volume criteria and restrict the volumes on which a user can install.
This script is usually used to check for software dependencies on each volume, such as the operating system installed on that volume. Installation scripts perform tasks you deem necessary to prepare for installation and to clean up after an installation is completed. Use these scripts to create needed files, add configuration options to existing files, start and stop services, and verify that setup is done correctly. These are the default installation scripts:.
The following list shows the order in which the scripts are executed and the point at which the actual installation takes place:. When a package script is run, four arguments are automatically passed to it that contain information useful to the script:.
You can see numerous example scripts by examining other packages. In most cases, this is all that is necessary to allow your package to be installed on volumes other than your boot volume.
Remember that volume names commonly have spaces in them, so you should quote every path. A payload-free package is a package that contains no files to install, so the Installer application uses scripts to automate any process. Payload-free packages are created using the same methods as with regular packages, but with no installed files.
Payload-free packages contain only scripts that can automate tasks, as shown in the following figure. You can populate the resources folder with the same scripts as described in the previous section. Simply include the command in a postflight script in a payload—free package and ask the user to install the package by double—clicking it.
One way to use this method would be to create a Network Install image from a payload—free package containing a script that runs Apple Software Restore ASR over multicast to restore the local volume. For a list of the files that were installed by the package, enter the following command on the command line:. When Installer is installing a package, it uses the existence of a receipt to determine whether to install or upgrade.
Installer will also execute the preupgrade and postupgrade scripts instead of the preinstall and postinstall scripts that are run during an install.
