# Bluefin / rpm-ostree / bootc dev-environment setup for Magic Civilization
#
# Installs the Linux-host packages that this project's tooling needs
# but that are NOT in the base ublue/bluefin image:
#
#   - weston            — Wayland compositor used by the headless
#                         Godot screenshot pipeline + Phase Gate proof
#                         scenes (runs flatpak Godot inside a weston
#                         session so viewport capture produces real
#                         pixels instead of the dummy-driver null).
#   - vulkan-tools      — vulkaninfo / vkcube; diagnostic binaries for
#                         probing the installed Vulkan stack.
#   - mesa-vulkan-drivers — always present on ublue; redeclared here so
#                         this script is a complete dev-deps manifest.
#
# Idempotent: re-running is a no-op once packages are installed. Uses
# `rpm-ostree install --apply-live` so the packages are usable in the
# current boot without waiting for reboot. PERSISTENCE across reboots
# comes from layering in the bootc image
# (`~/Code/bootc-bluefin/containerfiles/Containerfile.desktop-core`);
# this script runs the transient install for fast iteration.
#
# Usage:
#   ./run setup:bluefin            # install missing packages
#   ./run setup:bluefin --check    # exit 0 if all present, 1 otherwise
#
# Safe to run as your normal user — internally escalates with `sudo -n`
# for the one rpm-ostree call. If passwordless sudo is not configured,
# you'll be prompted for a password once.
