Software Packaging

Software Package Structure

Group related files in the source filesystem that will directly translate to the destination filesystem.

Software Elements

A software package is created from a hierarchy of software elements, which are structured and defined in a PSF. The SPB-specific software elements are as follows:

File

A file is the lowest level of software element that can be

 

contained in a software package. Files are grouped

 

together to create filesets.

Fileset

A fileset serves as a container for files, associated file

 

attributes, and separate control scripts. A fileset is

 

comprised of a group of files. Filesets are grouped and

 

contained in products. A fileset can only belong to one

 

product; however, a fileset may be referenced in

 

multiple subproducts within one product. A fileset can

 

also be included in multiple bundles through the

 

product it is contained within. A minimum of one

 

fileset is required for a PSF.

Product

A product is a container for filesets, subproducts,

 

and/or control scripts specific to a software package.

 

Products are collections that form a set of related

 

software. A product can contain one fileset or multiple

 

filesets. Products can contain filesets specific to

 

different versions of the product and different

 

hardware platforms. All these different filesets can be

 

packaged together for distribution. A minimum of one

 

product is required for a PSF.

Subproduct

A subproduct is a reference to groups of related filesets

 

within a product. For example, you might create a

 

subproduct that references a fileset grouping for the

 

entire runtime configuration, manuals, or

 

demonstration versions of the product. It is important

 

to remember that subproducts only reference filesets

 

and do not physically contain the fileset. The use of

 

subproducts is optional and considered an advanced

 

feature.
