Description of problem:
The livemedia-creator install is to a disk image. In RHEL 7 I was able to mount the install ISO in /mnt/install/repo and use the following kickstart url install method:
url --url="file:///mnt/install/repo"
With the same install method used in RHEL 9, livemedia-creator now throws the following message and exits:
The kickstart must activate networking if the url or nfs install method is used.

Version-Release number of selected component (if applicable):
lorax-34.9.14-1.el9.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Create the file test.ks with just one line:
url --url="file:///mnt/install/repo"
2. Run the following command:
livemedia-creator --no-virt --make-disk --ks=test.ks --image-only --dracut-arg=--no-hostonly --image-name image.tmp

Actual results:
The command fails with the following output:
[root@localhost i95code]# livemedia-creator --no-virt --make-disk --ks=test.ks --image-only --dracut-arg=--no-hostonly --image-name image.tmp

Expected results:

2022-10-05 15:45:52,371: Running anaconda.
and then anaconda will continue to install if there is a valid repo located at /mnt/install/repo

Additional info:lorax-28.14.68-1
This also affects the lorax that is shipped with the current RHEL 8.6 (lorax-28.14.68-1).
I already brought this issue up with the github lorax team and they have the following PR to resolve it: https://github.com/weldr/lorax/pull/1273
