之前有一台 Pi 3 閒置，查了一下記憶體有 1GB ，試試看吧！先把它更新到 Debian GNU/Linux 12 (bookworm) ，接著用 nvm 安裝出 node.js v22 環境，再調整 swap 到 1GB 來跑：

◇ Security ──────────────────────────────────────────────────────────────────────────────╮
│ │
│ Security warning — please read. │
│ │
│ OpenClaw is a hobby project and still in beta. Expect sharp edges. │
│ This bot can read files and run actions if tools are enabled. │
│ A bad prompt can trick it into doing unsafe things. │
│ │
│ If you’re not comfortable with basic security and access control, don’t run OpenClaw. │
│ Ask someone experienced to help before enabling tools or exposing it to the internet. │
│ │
│ Recommended baseline: │
│ - Pairing/allowlists + mention gating. │
│ - Sandbox + least-privilege tools. │
│ - Keep secrets out of the agent’s reachable filesystem. │
│ - Use the strongest available model for any bot with tools or untrusted inboxes. │
│ │
│ Run regularly: │
│ openclaw security audit --deep │
│ openclaw security audit --fix │
│ │
│ Must read: https://docs.openclaw.ai/gateway/security │

◆ I understand this is powerful and inherently risky. Continue?
