红帽全球峰会第 21 章 Kickstart script file format reference
This reference describes in detail the kickstart file format.
21.1. Kickstart file format
Kickstart scripts are plain text files that contain keywords recognized by the installation program, which serve as directions for the installation. Any text editor able to save files as ASCII text, such as Gedit or vim on Linux systems or Notepad on Windows systems, can be used to create and edit Kickstart files. The file name of your Kickstart configuration does not matter; however, it is recommended to use a simple name as you will need to specify this name later in other configuration files or dialogs.
- Commands
- Commands are keywords that serve as directions for installation. Each command must be on a single line. Commands can take options. Specifying commands and options is similar to using Linux commands in a shell.
- Sections
-
Certain special commands that begin with the percent
%character start a section. Interpretation of commands in sections is different from commands placed outside sections. Every section must be finished with the%endcommand. - Section types
The available sections are:
-
Add-on sections. These sections use the
%addon addon_namecommand. -
Package selection sections. Start with
%packages. Use it to list packages for installation, including indirect means such as package groups or modules. -
Script sections. These start with
%pre,%pre-install,%post, and%onerror. These sections are not required. - Certificate sections. These sections could be used to include certificates to be used by installation. For more information, see Kickstart certificates section.
-
Add-on sections. These sections use the
- Command section
-
The command section is a term used for the commands in the Kickstart file that are not part of any script section or
%packagessection. - Script section count and ordering
-
All sections except the command section are optional and can be present multiple times. When a particular type of script section is to be evaluated, all sections of that type present in the Kickstart are evaluated in order of appearance: two
%postsections are evaluated one after another, in the order as they appear. However, you do not have to specify the various types of script sections in any order: it does not matter if there are%postsections before%presections. - Comments
-
Kickstart comments are lines starting with the hash
#character. These lines are ignored by the installation program.
Items that are not required can be omitted. Omitting any required item results in the installation program changing to the interactive mode so that the user can provide an answer to the related item, just as during a regular interactive installation. It is also possible to declare the kickstart script as non-interactive with the cmdline command. In non-interactive mode, any missing answer aborts the installation process.
If user interaction is needed during kickstart installation in text or graphical mode, enter only the windows where updates are mandatory to complete the installation. Entering spokes might lead to resetting the kickstart configuration. Resetting of the configuration applies specifically to the kickstart commands related to storage after entering the Installation Destination window.
