Dear All, > It seems like kickstart is what you are looking for.? > Is this what you were trying to do? Yes, kickstart is what I’m looking for. Let me detail my provisioning process: * Provision a VM with standard CentOS 7 NetInstall ISO & my post script. The file system is created on top of LVM * Export entire VM as custom ISO image to be loaded into physical hardware * Kickstart physical hardware using above exported custom image & different grub/isolinux configuration Although I could just use the same CentOS 7 NetInstall ISO & run all my post script to the physical HW, it may take a few hours, since post script is long, and I wonder if above process will speed up, since the VM has everything needed. If that process isn’t feasible, then I’ll just do the same thing for physical hardware. Thanks, - Xinhuan
