Creating you own ks.cfg file

Introduction

First of all, please understand that kickstart installation is a tricky business. If you are a novice do not expect a quick success. You need to be persistent as at the initial state you do not fully understand the mechanic of the process and typically make one or more mistakes. As the result your installation fails. RHEL documentation is weak and internet posts are often incomplete and contradictory so it takes some time to distill the necessary information and make the necessary number of experiments to succeed.

RESOLVED = CentOS ISO too big for DvD media Post by warron.french » Fri Jan 03, 2020 9:46 pm This file, CentOS-8-x-dvd1.iso, that I downloaded when the ISO first became available.
This server contains a mix of raw/unsigned packages and/or build logs It should be used mainly for testing purposes Please see this link for current versions of.

To download the official and up-to-date CentOS 7 ISO file, navigate to Our recommendation for non-enterprise environments is to download the DVD ISO option, which includes the GUI. We recommend the Minimal ISO option only for production enterprise environments. File Size ↓ Date ↓ Parent directory/-0README.txt: 2.4 KiB: 2020-Nov-06 22:32: CentOS-7-x8664-DVD-2009.iso: 4.4 GiB: 2020-Nov-04 19:37: CentOS-7-x8664-DVD-2009.

But this is a great productivity tool for mass install of the servers and if you are persistent you will eventually succeed and your efforts will be rewarded.

Also this is a pretty elegant solution that is worth learning, unlike, say, systemd ;-) So far Red hat did not manage to screw kickstart to the extent it screwed the whole RHEL7 distribution with systemd,; The also screwed Kickstart and now it is more capricious and less reliable. Often attempt to use it ends with 'Pane frozen' message.

Including kickstart files in the ISO presents some problems: the ISO9660 file structure is not designed for modification, everything has a strictly defined place with no room to extend files or directories.

The way to include ks.cfg file is to extract the whole ISO file structure to working directory, modify that, and re-create a new image (in bootable format) from this working directory.

There are several step you need to accomplish

There are too major approaches here:

Modify the boot (RHEL) or minimal (CentOS) image to create a minimal boot ISO which points to the kickstart file on NFS or HTTP. Which means that it picks up both the actual kickstart file and the ISO from the network. This is the most popular approach. and it is works reasonably well for VPN-based installation, if you are forced to work from home due to Covid-19 epidemic. In this case the use of even minimal ISO (which actually is not that minimal and for RHEL 7 approaches 1 GB) present bandwidth problems, if you need to retrieve it from you PC (situation with HP servers if you not have advanced ILO license and stuck to using virtual drive mapped to ISO on your PC). In this case you can delete /Packages directory creating much smaller image. Customarization work is limited to provided proper options for grub to access the kickstart file. The main advantage is that now you can modify kickstart file for each installation and improve it as you gain experience.
- This also solves the problem of ridiculously long boot time for HP servers with large memory and memory check on boot. For such servers the boot time can be 20 min or more. You have essentially unattended
