Add NVIDIA drivers to live images for 9, 10 and 10-Kitten

[alaurie]

Added 12 new kickstart configurations to support both GNOME and KDE desktops for AlmaLinux 9, 10, and 10-kitten
(available for x86_64 and aarch64 architectures):

• AlmaLinux 9: GNOME/KDE ( x86_64 , aarch64 )
• AlmaLinux 10: GNOME/KDE ( x86_64 , aarch64 )
• AlmaLinux 10-Kitten: GNOME/KDE ( x86_64 , aarch64 )

Key details inside the kickstarts:

• Added the almalinux-nvidia repository pointing to the AlmaLinux CUDA repo.
• Modified the %post script to install the driver packages ( nvidia-open , libva-nvidia-driver , and
almalinux-release-nvidia-driver where applicable) inside the chroot environment.
• Configured dynamic initramfs regeneration inside %post to bundle the NVIDIA kernel modules on the Live Media.

🛠 Modifications & Enhancements

1. Build Script ( build-livemedia.sh )

• Added a new --with-nvidia option.
• Restricts NVIDIA driver installation only to supported versions (AlmaLinux 9+) and architectures (excludes
x86_64_v2 ).
• Dynamically adjusts output paths, ISO names, and volume labels when --with-nvidia is enabled (adding -NVIDIA
suffixes).
• Quality-of-life improvement: Automatically removes the previous build results directory if it already exists
(previously, livemedia-creator would fail if the output directory wasn't manually deleted beforehand).

2. GitHub Actions workflows

• .github/actions/shared-steps/action.yml : Added the new with_nvidia input parameter, updated output
directory paths, and passed the --with-nvidia flag to the build script.
• .github/workflows/build-media.yml : Added a with_nvidia boolean workflow input and conditionally skipped
x86_64_v2 architecture builds since NVIDIA drivers are not supported on it.

3. Documentation & Repository Configurations

• README.md : Updated documentation to detail NVIDIA GPU driver build support, explain the --with-nvidia flag,
and list necessary local dependencies (such as enabling the filelists metadata option in DNF config).
• .gitignore : Added rule to exclude local /results directories from being tracked.

🧪 Testing Verification

• Built live media locally (Alma 10 amd64).
• Booted generated amd64 Alma 10 KDE and Gnome ISO and confirmed Nvidia driver present and working.
• Confirmed that output files are correctly structured with the -NVIDIA suffix.
• Verified that x86_64_v2 builds are properly excluded when --with-nvidia is set.
