QA:Testcase install repository NFS variation

Description

This is to verify that Anaconda's inst.repo boot option works together with an NFS repository.

Setup

1. You need to have a Fedora repository accessible over an NFS protocol. If you do have it, no further setup is needed. If you don't, you can mount a DVD.iso image and export it over NFS this way:
   • Mount the image over loopback: # mount -o loop Fedora-42-x86_64-DVD.iso /mnt/repo
   • Install nfs-utils.
   • Let's say your (virtual) test machine is in the 192.168.1.0/24 subnet. Put the following line into /etc/exports:

     /mnt/repo    192.168.1.0/24(ro)

   • Restart NFS service: # systemctl restart nfs-server.service
   • The repository is now accessible over NFS via <your_IP>:/mnt/repo
2. Prepare any non-live media for booting the installer (anything except Live.iso).

How to test

1. Before booting the installer, specify a target NFS repository by adding a following boot option:

   inst.repo=nfs[:options]:<server>:/<path>

   Example:

   inst.repo=nfs:your_IP:/mnt/repo

   Make sure the repository architecture matches the architecture of your installer media.
2. Proceed with installation

Expected Results

1. The installer auto-selects requested NFS repository as the installation source in its GUI
2. The requested repository is used to download and install required packages. This can be checked by inspecting /tmp/packaging.log. Example output:
