# panel-native Rust runtime image.
#
# Rust's dedicated server is a native Linux binary (SteamCMD app 258550),
# so no Wine. We need:
#   - 32-bit runtime libs (RustDedicated is ELF64 but loads steamclient.so
#     which pulls in 32-bit deps).
#   - tini for signal forwarding (server does a graceful "Saving..." + exit
#     on SIGTERM when its RCON is unreachable).
#   - SDL/GL shims — Rust dedicated server does NOT need a display, but it
#     dlopens libGL and a couple of X libs at startup; we ship the stubs.
#
# Expected runtime layout inside the container:
#   /game                              — SteamCMD install (panel volume)
#   /game/RustDedicated                — server binary
#   /game/server/<identity>/           — world + save data (symlinked to /game-saves)
#   /game-saves                        — save + logs volume
#   /entrypoint.sh                     — boot script (seeds cfg, launches binary)
