Redhat – How to make kickstart exit

kickstartredhat

Is there a way to make a RedHat kickstart installation exit during the %pre% section? I have a condition I'm checking, and if it's true, I'd like the installation to not continue. I have tried using the "exit" and "init" commands, but all I can get it to do is to exit out of the %pre% section, but it still continues with the installation. Is there a different command, or completely different method, of forcing kickstart to exit before it starts making any changes to the system?

This should accomplish what you're looking for:

%pre --erroronfail

If the pre-installation script fails, this option will cause an error dialog to be displayed and will halt installation. The error message will direct you to where the cause of the failure is logged.

As Mircea mentioned setting up a PXE infrastructure would be the best choice if you are able.

You mention that you are using a kickstart templating system, if you are using Cobbler then I would suggest having a look at the command "cobbler-boo-iso" as you can build boot ISO images which can allow for network based installs. These boot iso images are designed to work in non-dhcp environments.

If all you are wanting to to is to change the ISO image you will need to mount it and copy the full contents. Then you will edit the boot/grub/boot.lst file. (I'm going from memory so I might be a little off.) Next you will need to rebuild the ISO disk and make it bootable. Here is an example:

$ mkisofs -o ~/rhel-6-disk.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -J -R -V disks ~/rhel-6-disk

I use CentOS, but the easiest way I've found to configure a system via kickstart is to install and configure a system the way I want it to be, then look at /root/anaconda-ks.cfg. That file is a kickstart the install you just did. I assume that Scientific has this file as well.

Once you have that file, I've found it much easier to modify (add/remove) what I want from that and it's taken care of the funny network, SELinux, iptables config, etc, for me.
