Post-Installation Script
You can also add commands to execute on the system after the installation is completed. If you have properly configured the network in the kickstart file, the network is enabled. If you would like to include a post-installation script, type it in the text area.
 | Caution |
|---|---|
Do not include the %post command. It will be 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 at the Section called Examples in Chapter 6. |
Chroot Environment
If you want your post-installation script to run outside of the chroot environment, click the checkbutton next to this option on the top of the Post-Installation window. This is equivalent to the using the --nochroot option in the %post section.
| Tip |
|---|---|
If you want to make any changes to the newly installed file system in the post-installation section outside of the chroot environment, you must append the directory name with /mnt/sysimage. |
For example, if you check the Run outside of the chroot environment button, the previous example needs to be changed to the following:
echo "Hackers will be punished!" > /mnt/sysimage/etc/motd |
Use an Interpreter
If you want to specify a scripting language to use to execute your script, click the Use an interpreter button and enter the interpreter in the text box beside the button. For example, /usr/bin/python2.2 can be specified for a Python script. This option corresponds to using %post --interpreter /usr/bin/python2.2 in your kickstart file.
