Installation parameters

The following four groups of parameters are available to all installation scripts. Some of the parameters can be modified by a request script, others cannot be modified at all.

The four installation parameters that are generated by installation software are described below:

PATH
Specifies the search list used by sh to find commands; PATH is set to /sbin:/usr/sbin:/usr/bin:/usr/sadm/install/bin upon script invocation.

UPDATE
Indicates that the current installation is intended to update the system. Automatically set to true if the package being installed is overwriting a version of itself.

PKGINST
Specifies the instance identifier of the package being installed. The value is equal to the package abbreviation (i.e., the same value as the PKG variable in the pkginfo file). See ``2. Defining a package instance'' for more details.)

PKGSAV
Specifies the directory where files can be saved for use by removal scripts or where previously saved files may be found.
