The node ID of an uvuyo node specifies which configuration it is going to pick at startup. The default node ID is “uvuyo”. You can specify the node ID of the uvuyo node by either adding the --uvuyo.nodeid to the command line of uvuyo or by setting the $UVUYO_NODEID environment variable.
If you use the uvuyo.sh wrapper shell script to start the uvuyo node you need to set the node ID using the environment variable since the wrapper script does not pass any command line arguments to uvuyo.
