Installation guide

the asterisk. The installation program defines several groups that contain related packages.
Refer to the variant/repodata/comps-*.xml file on the first Red Hat Enterprise Linux CD-ROM
for a list of groups. Each group has an id, user visibility value, name, description, and package
list. In the package list, the packages marked as mandatory are always installed if the group is
selected, the packages marked default are selected by default if the group is selected, and the
packages marked optional must be specifically selected even if the group is selected to be in-
stalled.
In most cases, it is only necessary to list the desired groups and not individual packages. Note
that the Core and Base groups are always selected by default, so it is not necessary to specify
them in the %packages section.
Here is an example %packages selection:
%packages
@ X Window System
@ GNOME Desktop Environment
@ Graphical Internet
@ Sound and Video dhcp
As you can see, groups are specified, one to a line, starting with an @ symbol, a space, and then
the full group name as given in the comps.xml file. Groups can also be specified using the id for
the group, such as gnome-desktop. Specify individual packages with no additional characters
(the dhcp line in the example above is an individual package).
You can also specify which packages not to install from the default package list:
-autofs
The following options are available for the %packages option:
--nobase
Do not install the @Base group. Use this option if you are trying to create a very small sys-
tem.
--resolvedeps
The --resolvedeps option has been deprecated. Dependencies are resolved automatically
every time now.
--ignoredeps
The --ignoredeps option has been deprecated. Dependencies are resolved automatically
every time now.
--ignoremissing
Ignore the missing packages and groups instead of halting the installation to ask if the in-
stallation should be aborted or continued. For example:
%packages --ignoremissing
