=> You  receive this  message  of  the  day  because  of  the  fastinit
   configuration.  To change the runlevel, refer to manpage fastinit(8)
   which is not shipped in this image. Message of the day should not be
   printed to serial output because it will confuse the rover.
=> Heavy serial outputs like this affect performance.
=> Uptime: $(uptime)
