4.2 Understanding
Maintenance Levels
Software products include those shipped with AIX and
those purchased separately. Each software product can contain separately
installable parts. The following list explains how software products are
organized.
-
Licensed Program
- A licensed program (also known as a product) is a
complete software product including all packages associated with that licensed
program. For example, the BOS (Base Operating System) is a licensed program.
-
Package
- A group of separately installable units that provide a
set of related functions. For example, bos.net is a package.
-
Fileset
- An individually installable option. Filesets provide a
specific function. For example, bos.net.nfs.client 4.3.0.0 is a fileset.
-
Fileset Update
- An individually installable update. The fileset update
either enhances or corrects a defect in a previously installed fileset. For
example, bos.net.nfs.client 4.3.0.3 is a fileset update.
-
Bundle
- A collection of packages, products, or individual
filesets that suit a specific purpose, such as providing personal productivity
software or software for a client machine in a network environment. A set of
bundles is provided with the BOS that contain a specific set of optional
software. The user_bundles directory is where users can
create their own bundle files.
