Post-Installation Script

Figure 2.16. Post-Installation Script


You can also add commands to execute on the system after the installation is completed. If the network is properly configured in the kickstart file, the network is enabled, and the script can include commands to access resources on the network. To include a post-installation script, type it in the text area.

Warning

Do not include the %post command. It is added for you.
For example, to change the message of the day for the newly installed system, add the following command to the %post section:
 echo "Hackers will be punished!" > /etc/motd 

Tip

More examples can be found in Section 1.7.1, “Examples”.

2.11.1. Chroot Environment

To run the post-installation script outside of the chroot environment, click the checkbox next to this option on the top of the Post-Installation window. This is equivalent to using the --nochroot option in the %post section.
To make changes to the newly installed file system, within the post-installation section, but outside of the chroot environment, you must prepend the directory name with /mnt/sysimage/.
For example, if you select Run outside of the chroot environment, the previous example must be changed to the following:
 echo "Hackers will be punished!" > /mnt/sysimage/etc/motd
