V,
If you're adding rpms then you'll need to update the repo to actually include
them. I'm not familiar with Lorax so I can't really help there, but if your end
goal is a standard RHEL dvd with extra packages that you want to define in
your kickstart configuration then it should just require createrepo and
genisoimage.
My use case is fairly vanilla kickstart you might have to modify to suit your
workflow.
- isolinux and efi use the inst.ks and inst.stage2 to point to kickstart file
and installation source respectively.
- kickstart file and pre/post/conf scripts in DVD/kickstart directory structure
- Packages in the default DVD/Packages and additional packages in
/DVD/Packages-Extra
- I delete all uneeded packages to reduce DVD size, just feed the rpm -qa
output on an installed system to yumdownloader
Here's a script stub - I do something similar in-house to get our DVDs created
for air-gapped environments (it's a pain).
Hope this helps 😊

Subject: Custom ISO with Kickstart and Local Repos

Hello,
I’m trying to create a custom ISO with a Kickstart file to achieve a complete
offline installation.
I was able to create the Kickstart file as usual, since I use it for PXE
installs for at least 10 years, but the major problem now is building the ISO
with the necessary files.
I’ve came across a tool named Lorax, but I was not able to create a custom ISO
from DVD’s. It only works when point to mirrors, and this is a time consuming
task. Another problem is that Lorax does not seems to care about the
/usr/share/lorax/product folder to create a custom Anaconda with the embedded
kickstart file on /usr/share/anaconda/interactive-defaults.ks.
The small ISO generated by Lorax lacks local repositories and I was unable to
find the appropriate documentation on how to build this scenario. So it
generates a boot only install that must be done over the Internet.
At this moment I’m running Lorax on a CentOS install, I’ve got RHEL licenses
too, but to keep it simple I just went with CentOS. I think this is irrelevant
information but it’s just for the sake of completion.
With genisoimage I was able to add the custom product.img file, that I’ve
generated by hand with cpio, on the ISO but I was not able to solve the local
repos problem. There are packages that I would like to add to the install
media, like Ansible, but they are available only on the Extras repository and
I’m unsure on how to do this. Just wondering if createrepo and yumdownloader
are necessary...
Any help is greatly appreciated.
Thanks,
V.
