  -ntargets int
        number of storage targets to expect at startup (hint, proxy-only)
  -transient
        false: apply command-line args to the configuration and save the latter to disk
        true: keep it transient (for this run only)
  -stderrthreshold value

Use --help for the most recently updated set of command-line options, for instance:

$ $GOPATH/bin/aisnode --help

Example command-line:

$ $GOPATH/bin/aisnode -config=/etc/ais.json -local_config=/etc/ais_local.json -role=target -daemon_id=aistarget1

Above command starts a target daemon with daemon ID aistarget1 using the global and local config from paths /etc/ais.json and /etc/ais_local.json respectively.
