+Description=Clawstor cluster daemon (gossip + RPC + Prometheus + build cache)
+Documentation=https://git.redclaw.dev/clawverse/clawstor
+After=network-online.target
+Wants=network-online.target
+
+[Service]
+Type=simple
+# Set both CLAWSTOR_BIN + CLAWSTOR_CONFIG via `systemctl edit
+# clawstor-cluster.service` — the drop-in replaces this unit's
+# ExecStart when the operator wants a non-default install.
+Environment=CLAWSTOR_BIN=%h/clawstor-deploy/claw-store
+Environment=CLAWSTOR_CONFIG=%h/clawstor-deploy/config.toml
+# rustc must be on PATH so the fingerprint gossip probe finds it.
+# `%h/.cargo/bin` is where rustup normally installs it. Adjust via
+# drop-in if your toolchain lives elsewhere.
+Environment=PATH=%h/.cargo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
+Environment=RUST_LOG=info
+ExecStart=/bin/sh -c '"$CLAWSTOR_BIN" --config "$CLAWSTOR_CONFIG" daemon'
+Restart=on-failure
+RestartSec=10
+# Give the daemon 60s to shut down cleanly (gossip needs to
+# advertise its intent so peers observe departure quickly). Longer
+# than default so a slow gossip round can complete.
+TimeoutStopSec=60
+
+# Security hardening — safe defaults for a build-cache daemon:
+NoNewPrivileges=yes
+ProtectSystem=strict
+ProtectHome=read-only
+# The blob-store root + hot/warm dirs are the only writable paths.
+# Adjust via drop-in when your dirs live outside `%h/clawstor-deploy`.
