Fedora 43 Post-Installation Setup Script

This script automates post-install configuration on Fedora 43, enabling common repositories, installing key applications, configuring storage, and applying AMD GPU kernel tuning for AMD setups.

What it does

• Hostname & identity

  • Sets system hostname and pretty hostname.
  • Assumes a primary user (name and group) for ownership of created resources.

• RPM Fusion repositories

  • Enables RPM Fusion Free and Nonfree for your current Fedora release.
  • Refreshes package metadata after enabling the repos.

• Multimedia codecs

  • Installs ffmpeg, OpenH264, and a curated set of GStreamer plugins for broad media playback support (avoids fragile DNF group names).

• Secondary drive setup

  • Looks up a drive by filesystem label (e.g. games).
  • Creates a mount point with chosen owner, group, and permissions.
  • Adds an idempotent UUID=… entry to /etc/fstab and runs mount -a.

• Desktop applications (DNF)

  • Optionally installs:
    • Steam
    • Discord
    • Syncthing
    • Git

• Flatpak & Flathub

  • Installs Flatpak if missing.
  • Adds the Flathub remote (only if not already present).
  • Optionally installs:
    • Signal (Flatpak)
    • Beyond All Reason (Flatpak)

• VSCodium

  • Adds the VSCodium RPM repository (with GPG key).
  • Installs the codium package.

• NVIDIA (optional)

  • Optionally installs NVIDIA akmods and CUDA-enabled driver packages.

• AMD GPU kernel parameters (Framework 16)

  • Optionally configures GRUB_CMDLINE_LINUX_DEFAULT with:
    • amdgpu.dcdebugmask=0x10
    • amdgpu.ppfeaturemask=0xffffffff
  • Regenerates the GRUB configuration and prompts for reboot.

All operations are idempotent: re-running the script will not duplicate configuration or re-add identical entries.

Usage

1. Clone and enter the repository

   git clone <repository-url>
   cd <repository-directory>
