For the example hardened systemd file, which is derived from config files which Synadia uses in production, add more examples:

  • Show setting GOMEMLIMIT env var
    • but also nudge towards using the external environment file for it
  • Use an external environment config file if it exists
  • Show mount-point dependency for JetStream
  • Configure automatic restarts
  • Show using InaccessiblePaths to lock down FS access even further
  • Setup a service alias of simply 'nats'.
