# One-time host setup for rootless OpenClaw in Podman: creates the openclaw
# user, builds the image, loads it into that user's Podman store, and installs
# the launch script. Run from repo root with sudo capability.
#
# Usage: ./setup-podman.sh [--quadlet|--container]
# --quadlet Install systemd Quadlet so the container runs as a user service
# --container Only install user + image + launch script; you start the container manually (default)
# Or set OPENCLAW_PODMAN_QUADLET=1 (or 0) to choose without a flag.
#
# After this, start the gateway manually:
# ./scripts/run-openclaw-podman.sh launch
# ./scripts/run-openclaw-podman.sh launch setup # onboarding wizard
# Or as the openclaw user: sudo -u openclaw /home/openclaw/run-openclaw-podman.sh
# If you used --quadlet, you can also: sudo systemctl --machine openclaw@ --user start openclaw.service
