# Simplified entrypoint for e2e testing
# 
# This script intentionally runs as root for e2e test environments to:
# 1. Simplify test setup and avoid permission-related test failures
# 2. Eliminate dependency on Alpine-specific tools (su-exec) since we use Ubuntu base
# 3. Focus testing on application logic rather than container security
#
# IMPORTANT: Production deployments should use Dockerfile.go_build with proper
# user isolation via su-exec. This simplified approach is ONLY for testing.
