Product
Represents a whole product, for example openSUSE®.
Pattern
A pattern is an installable group of packages dedicated to a certain purpose. For
example, the Laptop pattern contains all packages that are needed in a mobile
computing environment. Patterns dene package dependencies (such as required
or recommended packages) and come with a preselection of packages marked
for installation. This ensures that the most important packages needed for a
certain purpose are available on your system after installation of the pattern.
However, not necessarily all packages in a pattern are preselected for installation
and you can manually select or deselect packages within a pattern according to
your needs and wishes.
Package
A package is a compressed le in rpm format that contains the les for a particular
program.
Patch
A patch consists of one or more packages and may be applied by means of
deltarpms. It may also introduce dependencies to packages that are not installed
yet.
Resolvable
An generic term for product, pattern, package or patch. The most commonly used
type of resolvable is a package or a patch.
deltarpm
A deltarpm consists only of the binary di between two dened versions of a
package, and therefore has the smallest download size. Before being installed,
the full RPM package is rebuilt on the local machine.
Package Dependencies
Certain packages are dependent on other packages, such as shared libraries. In
other terms, a package may require other packages—if the required packages
are not available, the package cannot be installed. In addition to dependencies
(package requirements) that must be fullled, some packages recommend other
packages. These recommended packages are only installed if they are actually
available, otherwise they are just ignored and the package recommending them
is installed nevertheless.
