The agent-side enroll-bundle templates (decnet/web/templates/*) always set DECNET_SYSTEM_LOGS + StandardOutput/StandardError to a per-unit file under /var/log/decnet. The master-side init templates (deploy/*) never did, so every 'decnet init'-installed service: - inherited the default DECNET_SYSTEM_LOGS=decnet.system.log — a relative path, landing in the unit's WorkingDirectory. All 13 units shared the same cwd and fought for the same file, or more often just failed to write it under ProtectSystem=full, - emitted stdout/stderr to the journal by default, which is fine for uvicorn's INFO banter but makes per-service grepping a pain when you're chasing a single worker's trace. Mirror the agent-side wiring on all 13 master templates: - Environment=DECNET_SYSTEM_LOGS=/var/log/decnet/decnet.<name>.log - StandardOutput=append:/var/log/decnet/decnet.<name>.log - StandardError=append:/var/log/decnet/decnet.<name>.log /var/log/decnet is already in ReadWritePaths so ProtectSystem=full stays compatible. Operators now get a dedicated /var/log/decnet/decnet.<unit>.log per service, both from the app's structured logger and from any stray stderr — journalctl still works too, but no longer the only option.
