The kiosk dnf transaction was measured at 229 pkgs / 1.0 GB. Nearly all
of the non-core packages are Recommends: a locked-down single-URL kiosk
never uses flatpak + its ostree/bubblewrap sandbox runtime, tracker-miners
(a filesystem indexer — dead weight and a threat surface), the pipewire/
pulseaudio audio stack, or libproxy-webkitgtk4 -> webkit2gtk3-jsc (an 8.9M
second browser engine dragged into a Chromium kiosk for libproxy's PAC
runner).
Add --setopt=install_weak_deps=False to cut them, and an rpm -qa size
manifest to the build log so the next CI build reports the exact new
footprint (turning 'seems unnecessary' into data for the next trim round:
gstreamer/media codecs, or mesa-dri-drivers if the GPU path is abandoned).
The immovable floor is chromium + chromium-common + llvm-libs (mesa sw-GL)
+ gtk3/adwaita + libicu, all hard deps. BENCH-VERIFY the kiosk still
renders with weak deps off (watch for a missing font or libva).
