Creating a Linux Based (CentOS) Kickstart iso Install file

Posted on 2013-05-11

Hi All,

I'm trying to create a custom CentOS iso using Kickstart and I'm following this example.

I have a VirtualBox CentOS 6.4 32 bit install that was installed using the appropriate iso file.  I've created my Kickstart configuration file and I'm ready to run the below command to create the custom install in /root/test/ but I don't know what to supply for the -o and the -c parameters.  I have all the rpm's from the iso file used to create this CentOS VirtualBox insall in /root/kickstart_build/all_rpms.  

mkisofs Questions:
-What should I specify for -o without a iso file?  
-Regarding -c, I don't have a isolinux/ file, but I do have a boot.msg, is that the same?

Command to Generate the custom iso using Kickstart:
#cd /root/test/ &&
mkisofs -o /home/fedora-kickstart.iso -b isolinux/isolinux.bin -c isolinux/ -no-emul-boot -boot-load-size 4 -boot-info-table -J -R -V “Fedora” .

-o introduces the name of the file you are going to create. That will be an ISO9660 image, because that's what mkisofs always creates.
-c identifies the name of a file which mkisofs will create. This file must not exist in your source tree. So go ahead and specify isolinux/
