 `--install` 拒绝非空目录，不覆盖既有配置。该包安装青龙及其 Node 生产依赖；首次启动仍需已有 Python、Bash、PM2、nginx 等相应运行环境，不会在线安装或替换它们。服务启动和系统自启按原手动安装流程配置。
 
+ARMv6 glibc 小设备（例如 Raspberry Pi 1/Zero 的 Raspbian/Raspberry Pi OS 32 位系统）选择 `linux-armv6-glibc.tar.gz`，以同一安装器执行上述离线命令。该包要求 glibc >= 2.31、ARMv6 硬浮点 Node >= 20.18.1，不适用于 ARMv5、软浮点 Node 或旧版 glibc。安装和升级均不需要 Docker，也不会下载或替换 Node。
+
 ## 平台兼容
 
 - 最低 Node 为 20.18.1，Node-API 至少 6；安装器只检查，不替换 Node。
 - 以 Node 实际运行架构、ARM 指令集和 libc 类型/版本选择包；不依据 Docker 架构别名猜测。
 - glibc、musl 分包，并记录构建系统 libc 下限。系统库仍以目标设备加载测试作为最后检查。
+- ARMv6 glibc 使用签名校验的 Raspbian bullseye（glibc 2.31）构建环境，以固定 SHA256 的 ARMv6 Node 20.18.1 头文件编译 SQLite，强制 `-march=armv6 -mfpu=vfp -mfloat-abi=hard`。CI 检查 ELF 的 ARMv6 和硬浮点标记，并在 QEMU ARM1176 下完成归档复验、SQLite 读写和空目录离线安装；验证辅助镜像按不可变摘要记录，不进入用户安装包。Debian ARMv7 镜像仅提供同次构建的应用文件，不复用其 Node、libc 或 SQLite 二进制。
 - ARMv6 与 ARMv7 使用不同包名。ARMv6 在目标镜像中从源码编译 SQLite，禁止复用 generic `arm` 的 ARMv7 预编译件；构建需通过加载和内存库读写，失败则不发布渠道。
 - ARMv6 的归档构建、在线更新工作进程及独立离线安装器使用 `--jitless`，避开 ARM1176 上 V8 的优化编译崩溃；保留现有 Node 二进制，正常面板进程的启动参数不变。依赖加载和 SQLite 读写仍由现有 Node 的独立进程验证。
 - tar 中允许 pnpm 的包内符号链接；拒绝绝对路径、越界路径、包外链接、硬链接、设备条目和经符号链接写入的条目。重启前再次校验依赖，暂存失败保留上一次可用的就绪包。
