# bolt 卸载脚本(POSIX sh,需 root;Linux 使用 systemd,macOS 使用 launchd)
#
# 用法(在目标设备上):
#   IPv4: curl -fsSL https://git.jocayn.qzz.io/jocay/bolt/raw/branch/main/deploy/uninstall.sh | sudo sh
#   IPv6: curl -fsSL https://git.draws.qzz.io/jocay/bolt/raw/branch/main/deploy/uninstall.sh | sudo sh
#   保留配置: ... | sudo sh -s -- --keep-config
#
# 选项:
#   --keep-config   保留配置(Linux: /etc/bolt.env;macOS: /Library/Application Support/bolt 与 /var/log/bolt)
#
# 注意:如果是通过 bolt 自己执行本脚本,最后停止服务时连接会断开,这是正常现象。
