Three changes to make a reproducible Fedora KDE host install: - ci/fedora-rpm.Dockerfile: parameterize the Fedora base (ARG FEDORA_VERSION, default 43) so the same builder produces the Bazzite (F43, libavcodec.so.61) and Fedora 44 (libavcodec.so.62) RPMs. A binary RPM is soname-coupled to its base, so each target Fedora needs its own build/channel. - spec: install punktfunk-kde-session.service (was in the tree but never packaged) with its ExecStart repointed from the dev source tree to the installed run-headless-kde.sh. This is the headless `kwin --virtual` session (KWIN_WAYLAND_NO_PERMISSION_CHECKS=1) the kwin backend needs — an interactive Plasma session refuses to hand its privileged zkde_screencast protocol to an external client, so a dedicated session is required. Not enabled by default (kwin hosts opt in). - ship packaging/kde/host.env as host.env.kde — the ready KWin appliance config (wayland-kde). Validated live on a Fedora 44 KDE box (RTX 4090): KWin virtual output + zero-copy dmabuf->CUDA->NVENC. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
punktfunk-host — RPM (Bazzite / Fedora Atomic) via the Gitea registry
punktfunk-host is published as an RPM to Gitea's RPM package registry in the public unom
org (group bazzite), so Bazzite / Fedora Atomic hosts layer and update it with rpm-ostree.
CI (.gitea/workflows/rpm.yml) builds and publishes on every push to main (a rolling
0.0.1-0.ciN.<sha> build) and on v* tags (a clean X.Y.Z-1). The RPM is built in the
Fedora 43 image (ci/fedora-rpm.Dockerfile) so its auto-generated library Requires
(libavcodec.so.NN, …) match Bazzite's sonames; the NVIDIA driver lib (libcuda.so.1) is
excluded — NVENC/EGL come from whatever NVIDIA stack the host runs (a weak Recommends).
This is the same package as the COPR / bootc
paths — same spec (punktfunk.spec) — just self-hosted in Gitea instead of COPR, mirroring the
Debian/apt setup.
Install on a Bazzite host (one-time)
# Add the repo. Our RPMs are unsigned, but Gitea GPG-signs the repo METADATA — so verify that
# (repo_gpgcheck=1) and skip the per-package signature check (gpgcheck=0). The signed metadata
# carries each package's SHA256, so authenticity still holds. (Don't just curl Gitea's served
# bazzite.repo — it sets gpgcheck=1, which fails on unsigned packages.)
sudo tee /etc/yum.repos.d/punktfunk.repo >/dev/null <<'REPO'
[gitea-unom-bazzite]
name=punktfunk (unom, Bazzite)
baseurl=https://git.unom.io/api/packages/unom/rpm/bazzite

REPO
# Layer the package, then reboot into the new deployment.
rpm-ostree install punktfunk
systemctl reboot
If
rpm-ostreecan't complete the metadata GPG check non-interactively, setrepo_gpgcheck=0(TLS-only trust to the self-hosted registry). Proper per-package signing (gpgcheck=1) would need a CI signing key +rpm --addsign— future hardening, not wired up.
After reboot, as the desktop user:
ujust add-user-to-input-group # virtual gamepads need /dev/uinput (re-login).
# Bazzite is atomic — use ujust, NOT `usermod -aG input`.
mkdir -p ~/.config/punktfunk
cp /usr/share/punktfunk/host.env.bazzite ~/.config/punktfunk/host.env # gamescope defaults
systemctl --user enable --now punktfunk-host
(See ../bazzite/README.md for the full appliance walkthrough —
udev/group, host.env, the Steam session unit, firewall, verify.)
Updates
rpm-ostree upgrade # pulls the newest punktfunk with the system update
systemctl reboot # rpm-ostree changes apply on reboot
Layered packages are re-resolved against their repos on every rpm-ostree upgrade, so the box
tracks new builds automatically (Bazzite's auto-update timer does this for you). To pin or stop
tracking: rpm-ostree override / rpm-ostree uninstall punktfunk.
Build an RPM locally
PF_VERSION=0.0.1 bash packaging/rpm/build-rpm.sh # -> dist/punktfunk-0.0.1-1.fcNN.x86_64.rpm
Run it inside the Fedora 43 builder image so the deps resolve and match Bazzite:
docker build -f ci/fedora-rpm.Dockerfile -t punktfunk-fedora-rpm ci
docker run --rm -v "$PWD:/src" -w /src punktfunk-fedora-rpm \
bash -lc 'git config --global --add safe.directory /src && PF_VERSION=0.0.1 bash packaging/rpm/build-rpm.sh'
A plain rpmbuild/COPR build with no pf_version/pf_release defines produces 0.0.1-1.
