Check NixOS configurations / eval-hosts (push) Failing after 11m23s
services.beszel.agent runs under DynamicUser=true with ProtectSystem = "strict" and no StateDirectory, so /var/lib/beszel-agent -- where the agent persists the fingerprint that locks its hub pairing to this machine (github.com/henrygd/beszel/discussions/1542) -- was never actually writable. Every restart silently failed to persist it and regenerated a fresh one in memory, permanently desyncing from whatever the hub had on record after the very first successful pairing. Affects every host importing modules/beszel/enable-agent.nix (nix-cache, server), not just full container rebuilds. Found via nix-cache showing "fingerprint mismatch" after being rebuilt post-outage; confirmed server was silently exposed to the same bug, just hadn't restarted since its first pairing. Fixed by declaring StateDirectory so systemd gives the dynamic user real persistent storage. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
