Roadmap #3 (install on other devices). Bazzite already ships gamescope + PipeWire + the NVIDIA stack, so the host slots in with minimal new deps (ffmpeg-libs from RPM Fusion + opus + libei). - packaging/rpm/punktfunk.spec — builds punktfunk-host from source (cargo), installs the binary + udev rule + systemd user unit + headless helpers; Requires/Recommends mapped from the Ubuntu bootstrap deps to Fedora. - packaging/bootc/Containerfile — layer punktfunk into a bazzite-nvidia bootc image for atomic, image-based installs. - packaging/bazzite/host.env — gamescope-default appliance config (spawned per session). - packaging/copr/ + packaging/README.md — COPR build-from-SCM settings + install docs (rpm-ostree and bootc paths), and why not Flatpak. - LICENSE-MIT + LICENSE-APACHE — materialize the declared `MIT OR Apache-2.0` (was unfiled); the RPM ships them. Not buildable on the Ubuntu dev box (no rpm tooling) — the COPR/Fedora build is operator-run; all spec-referenced files verified present and the cargo build is green.

Packaging punktfunk for Fedora / Bazzite
The punktfunk host is Linux-only and links system FFmpeg (NVENC), PipeWire, Opus and the NVIDIA driver. This directory packages it for the Fedora Atomic / Bazzite world (rpm-ostree + bootc), where most of those deps are already present.
packaging/
rpm/punktfunk.spec # the RPM (builds punktfunk-host from source with cargo)
bazzite/host.env # gamescope-default config for a Bazzite appliance
bootc/Containerfile # bake punktfunk into a Bazzite-based atomic image
copr/ # COPR build-from-SCM settings
What's needed beyond base Fedora
| Dependency | Where it comes from |
|---|---|
ffmpeg-libs with NVENC |
RPM Fusion nonfree (ffmpeg, not ffmpeg-free) |
NVIDIA driver (libnvidia-encode, libEGL_nvidia) |
Bazzite -nvidia images ship it; plain Fedora: akmod-nvidia + xorg-x11-drv-nvidia-cuda |
| gamescope, PipeWire, wireplumber | Bazzite ships these; plain Fedora: dnf install gamescope pipewire wireplumber |
opus, libei |
Fedora base / updates |
On Bazzite the only genuinely new runtime bits are ffmpeg-libs (RPM Fusion) + opus +
libei — the rest of the stack is already there. The default backend is gamescope
(packaging/bazzite/host.env), which the host spawns headless per session — no desktop login.
Option A — COPR (per-host, rpm-ostree install)
- Create a COPR project, enable build-from-SCM pointing at this repo, spec path
packaging/rpm/punktfunk.spec(seecopr/README.md). Under External Repositories add RPM Fusion nonfree soffmpeg-develresolves at build time. - On the Bazzite host:
# RPM Fusion (for the NVENC ffmpeg) — usually already enabled on Bazzite rpm-ostree install \ https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm \ https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm # enable the COPR + install punktfunk sudo wget -O /etc/yum.repos.d/_copr_punktfunk.repo \ https://copr.fedorainfracloud.org/coprs/enricobuehler/punktfunk/repo/fedora-$(rpm -E %fedora)/ rpm-ostree install punktfunk systemctl reboot
Option B — bootc (image-based, atomic)
Layer punktfunk into a Bazzite image once, then rebase any number of hosts onto it — no
per-host drift. See bootc/Containerfile:
podman build -t ghcr.io/<you>/bazzite-punktfunk -f packaging/bootc/Containerfile .
podman push ghcr.io/<you>/bazzite-punktfunk
# on the target:
sudo bootc switch ghcr.io/<you>/bazzite-punktfunk && systemctl reboot
First-run setup (either option)
sudo usermod -aG input "$USER" # virtual gamepads need /dev/uinput (then re-login)
mkdir -p ~/.config/punktfunk
cp /usr/share/punktfunk/host.env.bazzite ~/.config/punktfunk/host.env # edit (gamescope app, etc.)
systemctl --user enable --now punktfunk-host
Pair a stock Moonlight client (mDNS-discovered), or connect the native punktfunk/1 client.
Why not Flatpak?
The host needs unsandboxed access the zero-copy NVENC path, /dev/uinput, the PipeWire
graph and the compositor's privileged protocols — a Flatpak sandbox fights all of these.
An RPM (or the bootc layer) installs into the host system where those just work.
Building the SRPM/RPM locally (Fedora only)
git archive --format=tar.gz --prefix=punktfunk-0.0.1/ -o ~/rpmbuild/SOURCES/punktfunk-0.0.1.tar.gz HEAD
rpmbuild -ba packaging/rpm/punktfunk.spec # needs the BuildRequires from the spec
(Not buildable on Debian/Ubuntu — use a Fedora toolbox/container or COPR.)
