enricobuehler f85d51b9f9 feat(steamdeck): one-command host install + docs (build-on-device)
SteamOS is immutable read-only Arch, and the Deck is AMD (VAAPI) — so none of the
checked-in packaging (arch/sysext is NVENC-first + client-oriented, deb/rpm are
soname-mismatched) actually installs a working host on a Steam Deck. The proven path
(distrobox-built native binary + systemd-run units) was 100% manual. Make it one command.

- scripts/steamdeck/install.sh — idempotent installer: ensure the pf2 Debian-trixie
  distrobox + toolchain → build host (+web console) → write config (generated web login
  password) → raise UDP buffers to 32 MB + udev + input group (sudo, skipped gracefully
  if unavailable) → install + start punktfunk-host / punktfunk-web systemd USER services
  with linger. Flags: --open (accept unpaired clients), --no-web, --src=DIR. Builds
  on-device so a rebuild always matches the running SteamOS (no prebuilt-binary fragility
  across OS updates); VAAPI on the Deck's AMD GPU.
- scripts/steamdeck/update.sh — rebuild from current source + restart (config/pairings persist).
- scripts/steamdeck/README.md — deep reference (why on-device, what's installed, gotchas).
- docs-site: new "Steam Deck (Host)" guide + sidebar entry; install.md splits Arch from the
  Steam Deck host path; packaging/arch/README points Deck-host users here and corrects the
  stale "NVENC-only" note (VAAPI host encode landed).

Live-validated on the Deck: installer runs clean, both services come up, host listens
(QUIC :9777 + mgmt :47990), web serves (302→login); on a client connect it takes over the
Game-Mode gamescope session at the client's mode, captures via PipeWire, and VAAPI-encodes
(hevc_vaapi) — full pipeline confirmed in the host journal.

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.

👉 Ubuntu/Debian hosts install via apt from Gitea's package registry — see debian/README.md (apt update && apt upgrade for new builds).

👉 End-to-end Bazzite setup walkthrough (install → udev/group → host.env → service → firewall → verify → troubleshooting): bazzite/README.md. This file is the higher-level packaging rationale.

packaging/
  rpm/punktfunk.spec      # the RPM (builds punktfunk-host from source with cargo)
  bazzite/host.env        # gamescope-default config for a Bazzite appliance
  bazzite/README.md       # step-by-step Bazzite setup guide
  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.

The host's RPM is published to unom's self-hosted Gitea RPM registry (CI builds it on every push), mirroring the Debian/apt setup. Add one repo file, install, and track updates with rpm-ostree upgrade — no COPR account needed. Full guide: rpm/README.md.

REPO
rpm-ostree install punktfunk && systemctl reboot
# updates:  rpm-ostree upgrade && systemctl reboot

Option B — COPR (per-host, rpm-ostree install)

  1. Create a COPR project, enable build-from-SCM pointing at this repo, spec path packaging/rpm/punktfunk.spec (see copr/README.md). Under External Repositories add RPM Fusion nonfree so ffmpeg-devel resolves at build time.
  2. 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)

ujust add-user-to-input-group           # virtual gamepads need /dev/uinput (then re-login).
                                        # On Bazzite use ujust, NOT `usermod -aG input` (atomic OS — it won't stick).
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

# Management web console (pairing + status) — pulled in by default (the host RPM Recommends it;
# `--no-install-recommends` / headless-only boxes can skip it). Enable it and read the login password:
systemctl --user enable --now punktfunk-web
journalctl --user -u punktfunk-web-init | sed -n 's/.*password generated: //p'   # then open http://<host-ip>:3000

Pair a stock Moonlight client (mDNS-discovered), or connect the native punktfunk/1 client — via the web console at http://<host-ip>:3000 or directly.

⚠️ COPR caveat: COPR's mock chroot has no bun, so a COPR build produces only punktfunk + punktfunk-clientnot punktfunk-web. For the console on a COPR/bootc host, install from the Gitea RPM registry (Option A — it carries punktfunk-web), which is also why bootc/Containerfile installs from there rather than COPR.

Why not Flatpak (for the HOST)?

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.

👉 The client is a different story — it IS shipped as a Flatpak (the only viable Steam Deck install path: SteamOS /usr is read-only and lacks libadwaita/libSDL3). See flatpak/README.md. The client sandbox only needs the GPU render node, Wayland, PipeWire audio, the network and hidraw — all expressible as finish-args.

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.)
