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.
