Print the message of the day
This uses the Nerves.Runtime library. In the unlikely event that it's not available, it assumes the system isn't ready and doesn't print the MOTD.
Options:
:logo- a custom logo to display instead of the default Nerves logo. Pass an empty logo ("") to remove it completely.:extra_rows- a list of custom rows or a callback for returning rows. The callback can be a 0-arity function reference or MFArgs tuple.
