After your partitions have been selected and configured for formatting,
you are ready to select packages for installation.
 | Note |
|---|
| | Unless you choose a custom installation, the installation program will
automatically choose most packages for you. However, you must select either
GNOME or KDE (or both) to install a graphical environment.
|
GNOME and KDE are both graphical desktop environments[1] that handle the overall look and feel of your system. You
must choose one of these to have a default graphical setup, but you can
also install both to determine for yourself which you prefer.
If you do not have unlimited space (at least 1.7 GB) to install both
GNOME and KDE, the section called A Brief Introduction to GNOME and the section called A Brief Introduction to KDE should make the choice a little easier for
you.
You can select components, which group packages together according to
function (for example, C Development,
Networked Workstation, or Web
Server), individual packages, or a combination of the two.
To select a component, click on the checkbox beside it (see Figure 3-18).
Select each component you wish to install. Selecting
Everything (at the end of the component list)
during a custom installation installs all packages included with
Red Hat Linux. If you select every package, you will need approximately 1.7 GB
of free disk space.
To select packages individually, check the Select Individual
Packages box at the bottom of the screen.
After selecting the components you wish to install, you can select or
deselect individual packages. You can select or deselect packages
using your mouse (see Figure 3-19).
You can choose to view the individual packages in tree view
or flat view.
Tree view allows you to see the packages grouped by
application type.
Flat view allows you to see all of the packages in an
alphabetical listing on the right of the screen.
Using Tree view, you see a listing of package
groups. When you expand this list and pick one group, the list of
packages in that group appears in the panel on the right.
To sort alphabetically, click on the Package tab.
To sort packages by size, click on the Size (MB)
tab.
To select an individual package, double-click the checkbox beside the
package name. A check mark in the box means that a package has been
selected.
For more information about a specific package, click on the individual
package name. The package information will appear at the bottom of the
screen.
You can also select or deselect all packages listed within a
particular group, by clicking on the Select all in
group or Unselect all in group
buttons.
| Note |
|---|
| | Some packages (such as the kernel and certain libraries) are
required for every Red Hat Linux system and are not available to select or
deselect. These base packages are selected by default.

GNOME is a powerful graphics-driven desktop environment. GNOME
includes a panel (for starting applications and displaying status), a
desktop (where data and applications can be placed), multiple window
managers (which control the look and feel of your desktop), and a
standard set of desktop tools and applications.
GNOME allows you to set your desktop the way you want it to look and
"feel." GNOME's session manager remembers settings and currently
running programs. So, once you have set things the way you like, they
will stay that way.
Figure 3-20 shows a typical graphical environment
using the GNOME desktop environment. A typical graphical environment for KDE
would be similar.
Refer to the Official Red Hat Linux Getting Started Guide to learn more about GNOME.
KDE provides a complete desktop environment, including a file manager,
a window manager, an integrated help system, a configuration system,
numerous tools and utilities, and an ever increasing number of
applications.
KDE offers a contemporary desktop, a searchable help system with
convenient access to help on the use of the KDE desktop and its
applications, standardized menu and toolbars, keybindings, color
schemes, and more.
Refer to the Official Red Hat Linux Getting Started Guide to learn more about KDE.
Many software packages, in order to work correctly, depend on other
software packages that must be installed on your system. For example,
many of the graphical Red Hat system administration tools require the
python and pythonlib
packages. To make sure your system has all the packages it needs in
order to be fully functional, Red Hat Linux checks these package
dependencies each time you install or remove
software packages.
If any package requires another package which you have not selected to
install, the program presents a list of these unresolved dependencies
and gives you the opportunity to resolve them (see Figure 3-21).
The Unresolved Dependencies screen appears only
if you are missing packages that are needed by the packages you have
selected. At the bottom of the screen, under the list of missing
packages, an Install packages to satisfy
dependencies checkbox is selected by default. If you leave
this checked, the installation program will resolve package
dependencies automatically by adding all required packages to the list
of selected packages.
