# deploy.sh 的实测脚本
# ════════════════════════════════════════════════════════════════
#
# 这台开发机是 Windows（Git Bash），没有 systemctl / ip / iptables，
# 所以测试的做法是：
#   1. 造一个沙箱目录，用 deploy.sh 的 --prefix 把所有写入关在里面
#   2. 在 PATH 最前面放一批「桩命令」，把 Linux 专有的东西接住
#      （systemctl / ip / iptables / nmcli / cloudflared / curl …）
#   3. 同一个沙箱**跑两遍**，验证第二遍不报错、不把已有东西冲掉
#
# 验证的是：语法、参数解析、文件部署、unit 生成、幂等性。
# **不能**验证的：真实的 systemd 行为、iptables 真的有没有生效、
# 隧道能不能连上 —— 那些得在真的 Linux 机器上跑。
#
# 用法: bash _build/test_deploy_sh.sh
