Using Microvm.nix to Sandbox OpenClaw

> Node.js (which OpenClaw uses) calls os.networkInterfaces() at startup via libuv’s uv_interface_addresses, which needs AF_NETLINK to query interfaces through netlink. Without it, you get a cryptic Unknown system error 97. Took me a few deploy cycles to figure that one out.

I believe you can use other runtimes, but then certain connectors, like telegram, may break.
