SW_CATALOG
Holds the path to the Installed Products Database (IPD), relative to the path in the
SW_ROOT_DIRECTORY
environment variable. Note that you can specify a path for
the IPD using the
installed_software_catalog
default option.
SW_CONTROL_DIRECTORY
Defines the current directory of the script being executed, either a temporary catalog
directory, or a directory within in the Installed Products Database (IPD). This variable
tells scripts where other control scripts for the software are located (for example, sub-
scripts).
SW_CONTROL_TAG
Holds the tag name of the control_file being executed. When packaging software, you
can define a physical name and path for a control file in a depot. This lets you define the
control_file with a name other than its tag and lets you use multiple control file
definitions to point to the same file. A control_file can query the
SW_CONTROL_TAG
variable to determine which tag is being executed.
SW_LOCATION
Defines the location of the product, which may have been changed from the default pro-
duct directory. When combined with the SW_ROOT_DIRECTORY
, this variable tells
scripts where the product files are located.
SW_PATH A PATH variable which defines a minimum set of commands available for use in a con-
trol script (for example, /sbin:/usr/bin
).
SW_ROOT_DIRECTORY
Defines the root directory in which the session is operating, either / or an alternate root
directory. This variable tells control scripts the root directory in which the products are
installed. A script must use this directory as a prefix to SW_LOCATION to locate the
product’s installed files. The configure script is only run when
SW_ROOT_DIRECTORY
is /.
SW_SESSION_OPTIONS
Contains the pathname of a file containing the value of every option for a particular
command, including software and target selections. This lets scripts retrieve any com-
mand options and values other than the ones provided explicitly by other environment
variables. For example, when the file pointed to by
SW_SESSIONS_OPTIONS
is made
available to a request script, the targets option contains a list of
software_collection_specs for all targets specified for the command. When the file
pointed to by
SW_SESSIONS_OPTIONS
is made available to other scripts, the targets
option contains the single software_collection_spec for the targets on which the script is
being executed.
SW_SOFTWARE_SPEC
This variable contains the fully qualified software specification of the current product or
fileset. The software specification allows the product or fileset to be uniquely identified.
Additional environment variables that affect scripts run by
swinstall and swremove:
SW_CONFIG_AFTER_REBOOT
This variable should be read only by the configure script. If this is set to any value
it indicates the configure script was invoked by the swconfig command during
system startup. This variable is set by the /sbin/init.d/swconfig system
startup script.
SW_DEFERRED_KERNBLD
Only applies to swinstall. This variable is normally unset. If it is set, the actions
necessary for preparing the system file /stand/system cannot be accomplished from
within the postinstall scripts, but instead must be accomplished by the configurescripts.
This occurs whenever software is installed to a directory other than /, such as for a clus-
ter client system. This variable should be read only by the configure and postinstall
scripts of a kernel fileset. The swinstall command sets these environment variables
for use by the kernel preparation and build scripts.
SW_INITIAL_INSTALL
Only applies to swinstall. This variable is normally unset. If it is set, the swin-
stall
session is being run as the back end of an initial system software installation
