# =============================================================================
# KAMOS - Gaming OS - Containerfile
# "Play. Perform. Dominate."
# Base: Bazzite NVIDIA stable (proprietary NVIDIA driver, gaming-tuned bootc)
# =============================================================================
#
# Why this base:
#   ghcr.io/ublue-os/bazzite-nvidia:stable ships with the proprietary NVIDIA
#   driver baked in via akmods. If you want the open-kernel-module variant,
#   swap to ghcr.io/ublue-os/bazzite-nvidia-open:stable instead.
#
# Architecture: x86_64 only. This image will NOT boot natively on an Apple
# Silicon Mac. Test it inside VMware Fusion (with x86_64 emulation enabled)
# or install on a real NVIDIA PC.

# Stage 1: copy our customisations into the build context
# Note: build_files goes to /ctx (NOT /tmp) because the RUN below mounts a
# tmpfs over /tmp which would hide anything we put there.

COPY build_files/ /ctx/
COPY system_files/ /

# bootc install config - tells bootc-image-builder our rootfs is btrfs.
# Without a file under /usr/lib/bootc/install/, bib errors out with
# "missing required info: DefaultRootfs". 00- prefix loads first; any
# upstream Bazzite file with a higher prefix can still override.

# -----------------------------------------------------------------------------
# Stage 2: run the customisation script
#   - install / remove packages
#   - apply branding (wallpaper, plymouth theme, os-release, GRUB logo)
#   - any other system tweaks

# Sanity: make sure the image is bootc-compatible after our changes.
# `bootc container lint` is run by ostree container commit but we surface a
# friendly error via a final no-op so layer caching is clear.
