8.11. 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.
 | 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 |
8.11.1. 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
the using the --nochroot option in the
%post section.
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 select Run outside of the chroot
environment, the previous example needs to be changed to
the following:
echo "Hackers will be punished!" > /mnt/sysimage/etc/motd |
8.11.2. Use an Interpreter
To specify a scripting language to use to execute the script, select
the Use an interpreter option and enter the
interpreter in the text box beside it. 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.
