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.
